Title: Phenoxymethyl imidazoline derivatives and their use as pesticides

Description:
The present invention relates to imidazoline derivatives and their use as insecticidal, acaricidal, molluscicidal and nematocidal agents. The invention also extends to insecticidal, acaricidal, molluscicidal and nematicidal compositions comprising such imidazoline derivatives, and to methods of using such derivatives and/or compositions to combat and control insect, acarine, mollusc and nematode pests. In particular the present invention relates to imidazolines with alkyl and fluoro substituents. 
     A number of imidazoline derivatives with acaricidal or ectoparasiticidal properties are known, for example, from U.S. Pat. No. 4,226,876, U.S. Pat. No. 4,414,223, DE2818367, EP0011596, U.S. Pat. No. 4,276,302, U.S. Pat. No. 4,232,011, U.S. Pat. No. 4,241,075 and U.S. Pat. No. 4,233,306. In particular, U.S. Pat. No. 5,128,361 discloses fluorophenoxy-methyl-imidazoline derivatives useful for combating ectoparasites in host animals and JP51106739 discloses trifluoro- and fluoro-phenoxy-methyl-imidazoline derivatives which have some activity against ticks or mosquitoes. 
     We have now found further novel imidazoline derivatives, which have surprisingly good pesticidal activity, in particular surprisingly good insecticidal and/or acaricidal activity. Thus according to a first aspect of the invention there is provided a compound of formula (I):

     Compounds of the invention can be prepared by a variety of methods, for example those described below. 
     Compounds of the formula (I) in which Z is not H can be prepared from compounds of the formula (I) in which Z is H, by treatment with the appropriate reagent. Depending on the nature of Z this can be for example an alkylating agent, an acylating agent, a carbamoylating agent, a phosphorylating agent, a sulfenylating agent or an oxidising agent. These derivatisating agents are generally electrophiles. Methods for the conversion of NH groups into NZ groups can be found for example in T. W. Greene and P. G. M. Wuts “Protecting Groups in Organic Synthesis” 3 rd  Edition, Wiley, NY 1999. 
     
       
         
         
             
             
         
       
     
     Compounds of the formula (I) can be prepared by alkylation of a phenol of the formula (2), with a 2-haloalkylimidazoline of the formula 3 (J. Am. Chem. Soc. 1947, 69, 1688). 
     
       
         
         
             
             
         
       
     
     Compounds of the formula (I) can be prepared from nitriles of the formula (4), by treatment with a diamine of the formula (5). This is advantageously performed in the presence of a catalyst such as CS 2 , P 2 S 5  (J. of Med. Chem., 2003 46, 1962) or Na 2 S 4  (DE 2512513). The nitrile (4) can be converted to imidates of the formula (6) using an alcohol such methanol and a catalytic amount of base such as NaOH, or to imidate salts of formula (6) using an alcohol such as methanol or ethanol and an acid such as HCl. Imidates of the formula (6) can be converted to compounds of the formula (I) on treatment with diamines of the formula (5) (J. of Med. Chem., 2004, 47, 6160; J. Am. Chem. Soc. 1947, 69, 1688). Nitriles of the formula (4) can be prepared by alkylating phenols of the formula (2) with a nitrile of the formula (8), bearing a leaving group L 1  (J. Am. Chem. Soc. 1947, 69, 1688). 
     
       
         
         
             
             
         
       
     
     In a variant, anilines of formula (2a) can be reacted with nitriles of formula (8) to form compounds of the formula (4a). The amines of formula (4a) can be converted then to nitriles of formula (4), in which R 2  is fluoro, chloro, bromo or iodo by diazotisation and further conversion to the corresponding halide (H. Zollinger, “Diazo Chemistry 1, Aromatic and Heteroaromatic Compounds” VCH, Weinheim, 1994). 
     
       
         
         
             
             
         
       
     
     In another variant phenols of formula (2b), wherein Q is an aldehyde, acid or ester group, can be reacted with nitriles of formula (8) to compounds of formula (4b). Compounds of formula (4b) can then be converted to the corresponding compounds of formula (4), in which R 2  is C 1-2 haloalkyl, in particular difluoromethyl, fluoromethyl or trifluormethyl, by well-known functional group conversions. 
     
       
         
         
             
             
         
       
     
     To the man skilled in the art, it is understood, that in these variants any of the groups R 2 , R 3 , R 4 , R 5  and R 6  may be an amino group or a group Q for such further transformations. 
     Esters of the formula (7) can be converted to imidazolines of the formula (I) by treatment with diamines of the formula (5) (J. Am. Chem. Soc. 1950, 72, 4443-5). Alkylaluminium reagents can be used with advantage to facilitate this reaction. This conversion occurs in two steps by forming first the monoamide (10), which can serve as a precursor to imidazolines of the formula (I). Esters of the formula (7) can be prepared by alkylation of phenols of the formula (2) with esters of the formula (9), wherein L 2  is a leaving group, and Rxx is an optionally substituted alkyl or aryl group (typically C 1 -C 6  alkyl, phenyl or benzyl). The leaving groups L 1  and L 2  are typically those used for S N 2 reactions. L 1  and L 2  become anions of organic or inorganic acids on leaving their substrates (9) and (10). Typical leaving groups are for example halide such as chlorine or bromine, alkylsulfonates such as mesylate, and arylsulfonates such as tosylate. 
     
       
         
         
             
             
         
       
     
     Compounds of the formula (I) can be prepared from imidazolines of the formula (11) by introduction of a group R 1 . This can be done by treating (11) with a base and then subsequently with an electrophile capable of introducing the group R 1 . A typical electrophile could be a halide such as R 1 -Cl, R 1 -Br, or R 1 -I. A typical base could be n-butyllithium or mesityl-lithium. The Z group can be a protecting group such tBuOCO or (CH 3 ) 3 Si, which can be removed if desired, and a different Z group can be attached as described above if so desired. This process is exemplified in example 3. 
     
       
         
         
             
             
         
       
     
     Compounds of formula (2), (3), (5), (7), (8), (9) and (11) are known compounds or may be obtained readily from known compounds using processes that are routine in the art and with which the skilled man will be familiar. 
     The compounds of the formula (4), including those of formula (4a) and formula (4b), wherein R 1 , R 2 , R 3 , R 4 , R 5  and R 6  are as defined hereinbefore, have been specifically designed as intermediates for the synthesis of the compounds of the formula (I) and as such form yet a further aspect of the invention.

     In a further aspect of the invention the compounds of formula (I) can be used to combat and control infestations of insect pests such as Lepidoptera, Diptera, Hemiptera, Thysanoptera, Orthoptera, Dictyoptera, Coleoptera, Siphonaptera, Hymenoptera and Isoptera and also other invertebrate pests, for example, acarid, nematode and mollusc pests. Insects, acarids, nematodes and molluscs are hereinafter collectively referred to as pests. The pests which may be combated and controlled by the use of the invention compounds include those pests associated with agriculture (which term includes the growing of crops for food and fibre products), horticulture and animal husbandry, companion animals, forestry and the storage of products of vegetable origin (such as fruit, grain and timber); those pests associated with the damage of man-made structures and the transmission of diseases of man and animals; and also nuisance pests (such as flies). 
     Examples of pest species which may be controlled by the compounds of formula (I) include: Myzus persicae (aphid), Aphis gossypii (aphid), Aphis fabae (aphid), Lygus spp. (capsids), Dysdercus spp. (capsids), Nilaparvata lugens (planthopper), Nephotettixc incticeps (leafhopper), Nezara spp. (stinkbugs), Euschistus spp. (stinkbugs), Leptocorisa spp. (stinkbugs), Frankliniella occidentalis (thrip), Thrips spp. (thrips), Leptinotarsa decemlineata (Colorado potato beetle), Anthonomus grandis (boll weevil), Aonidiella spp. (scale insects), Trialeurodes spp. (white flies), Bemisia tabaci (white fly), Ostrinia nubilalis (European corn borer), Spodoptera littoralis (cotton leafworm), Heliothis virescens (tobacco budworm), Helicoverpa armigera (cotton bollworm), Helicoverpa zea (cotton bollworm), Sylepta derogata (cotton leaf roller), Pieris brassicae (white butterfly), Plutella xylostella (diamond back moth), Agrotis spp. (cutworms), Chilo suppressalis (rice stem borer), Locustamigratoria (locust), Chortiocetes terminifera (locust), Diabrotica spp. (rootworms), Panonychus ulmi (European red mite), Panonychus citri (citrus red mite), Tetranychus urticae (two-spotted spider mite), Tetranychus cinnabarinus (carmine spider mite), Phyllocoptruta oleivora (citrus rust mite), Polyphagotarsonemus latus (broad mite), Brevipalpus spp. (flat mites), Boophilus microplus (cattle tick), Dermacentor variabilis (American dog tick), Ctenocephalides felis (cat flea), Liriomyza spp. (leafminer), Musca domestica (housefly), Aedes aegypti (mosquito), Anopheles spp. (mosquitoes), Culex spp. (mosquitoes), Lucillia spp. (blowflies), Blattella germanica (cockroach), Periplaneta americana (cockroach), Blatta orientalis (cockroach), termites of the Mastotermitidae (for example Mastotermes spp.), the Kalotermitidae (for example Neotermes spp.), the Rhinotermitidae (for example Coptotermes formosanus, Reticulitermes flavipes, R. speratu, R. virginicus, R. hesperus, and R. santonensis) and the Termitidae (for example Globitermes sulphureus), Solenopsis geminata (fire ant), Monomorium pharaonis (pharaoh&#39;s ant), Damalinia spp. and Linognathus spp. (biting and sucking lice), and Deroceras reticulatum (slug). 
     The invention therefore provides a method of combating and controlling insects, acarids, or molluscs which comprises applying an insecticidally, acaricidally, nematicidally or molluscicidally effective amount of a compound of formula (I), or a composition containing a compound of formula (I), to a pest, a locus of pest, or to a plant susceptible to attack by a pest. The compounds of formula (I) are preferably used against insects or acarines. 
     The term “plant” as used herein includes seeds, seedlings, bushes and trees. 
     In particularly preferred embodiments, compounds of formula (I) and compositions containing such compounds are used in methods of controlling and combating insects in the orders Hemiptera, Lepidoptera, Coleoptera, Thysanoptera, Diptera, Blattodea, Isoptera, Siphonaptera, Hymenoptera, and/or Orthoptera. In certain embodiments, such compounds and compositions are particularly useful in controlling and combating Hemiptera, Lepidoptera, Coleoptera, Thysanoptera, or Diptera. In further embodiments such compounds and compositions are particularly useful in controlling and combating Lepidoptera, Thysanoptera, Isoptera, Siphonaptera, Hymenoptera, or Orthoptera. It is particularly preferred that compounds of formula (I), and compositions containing these compounds are used against Hemipteran insects. 
     In order to apply a compound of formula (I) as an insecticide, acaricide, nematicide or molluscicide to a pest, a locus of pest, or to a plant susceptible to attack by a pest, a compound of formula (I) is usually formulated into a composition which includes, in addition to the compound of formula (I), a suitable inert diluent or carrier and, optionally, a surface active agent (SFA). Suitable inert diluents or carriers are described herein, for example with respect to certain formulation types, and thus the term includes solid diluents, inorganic water soluble salts, water-soluble organic solids and the like as well as simple diluents such as, for example, water and/or oils. SFAs are chemicals which are able to modify the properties of an interface (for example, liquid/solid, liquid/air or liquid/liquid interfaces) by lowering the interfacial tension and thereby leading to changes in other properties (for example dispersion, emulsification and wetting). It is preferred that all compositions (both solid and liquid formulations) comprise, by weight, 0.0001 to 95%, more preferably 1 to 85%, for example 5 to 60%, of a compound of formula (I). The composition is generally used for the control of pests such that a compound of formula (I) is applied at a rate of from 0.1 g to 10 kg per hectare, preferably from 1 g to 6 kg per hectare, more preferably from 1 g to 1 kg per hectare. 
     When used in a seed dressing, a compound of formula (I) is used at a rate of 0.0001 g to 10 g (for example 0.001 g or 0.05 g), preferably 0.005 g to 10 g, more preferably 0.005 g to 4 g, per kilogram of seed. 
     In another aspect the present invention provides an insecticidal, acaricidal, nematicidal or molluscicidal composition comprising an insecticidally, acaricidally, nematicidally or molluscicidally effective amount of a compound of formula (I) and a suitable carrier or diluent therefor. The composition is preferably an insecticidal, acaricidal, nematicidal or molluscicidal composition. 
     In a still further aspect the invention provides a method of combating and controlling pests at a locus which comprises treating the pests or the locus of the pests with an insecticidally, acaricidally, nematicidally or molluscicidally effective amount of a composition comprising a compound of formula (I). Such compositions are preferably used against insects, acarids or nematodes. 
     The compositions can be chosen from a number of formulation types, including dustable powders (DP), soluble powders (SP), water soluble granules (SG), water dispersible granules (WG), wettable powders (WP), granules (GR) (slow or fast release), soluble concentrates (SL), oil miscible liquids (OL), ultra low volume liquids (UL), emulsifiable concentrates (EC), dispersible concentrates (DC), emulsions (both oil in water (EW) and water in oil (EO)), micro-emulsions (ME), suspension concentrates (SC), aerosols, fogging/smoke formulations, capsule suspensions (CS) and seed treatment formulations. The formulation type chosen in any instance will depend upon the particular purpose envisaged and the physical, chemical and biological properties of the compound of formula (I). 
     Dustable powders (DP) may be prepared by mixing a compound of formula (I) with one or more solid diluents (for example natural clays, kaolin, pyrophyllite, bentonite, alumina, montmorillonite, kieselguhr, chalk, diatomaceous earths, calcium phosphates, calcium and magnesium carbonates, sulphur, lime, flours, talc and other organic and inorganic solid carriers) and mechanically grinding the mixture to a fine powder. 
     Soluble powders (SP) may be prepared by mixing a compound of formula (I) with one or more water-soluble inorganic salts (such as sodium bicarbonate, sodium carbonate or magnesium sulphate) or one or more water-soluble organic solids (such as a polysaccharide) and, optionally, one or more wetting agents, one or more dispersing agents or a mixture of said agents to improve water dispersibility/solubility. The mixture is then ground to a fine powder. Similar compositions may also be granulated to form water soluble granules (SG). 
     Wettable powders (WP) may be prepared by mixing a compound of formula (I) with one or more solid diluents or carriers, one or more wetting agents and, preferably, one or more dispersing agents and, optionally, one or more suspending agents to facilitate the dispersion in liquids. The mixture is then ground to a fine powder. Similar compositions may also be granulated to form water dispersible granules (WG). 
     Granules (GR) may be formed either by granulating a mixture of a compound of formula (I) and one or more powdered solid diluents or carriers, or from pre-formed blank granules by absorbing a compound of formula (I) (or a solution thereof, in a suitable agent) in a porous granular material (such as pumice, attapulgite clays, fuller&#39;s earth, kieselguhr, diatomaceous earths or ground corn cobs) or by adsorbing a compound of formula (I) (or a solution thereof, in a suitable agent) on to a hard core material (such as sands, silicates, mineral carbonates, sulphates or phosphates) and drying if necessary. Agents which are commonly used to aid absorption or adsorption include solvents (such as aliphatic and aromatic petroleum solvents, alcohols, ethers, ketones and esters) and sticking agents (such as polyvinyl acetates, polyvinyl alcohols, dextrins, sugars and vegetable oils). One or more other additives may also be included in granules (for example an emulsifying agent, wetting agent or dispersing agent). 
     Dispersible Concentrates (DC) may be prepared by dissolving a compound of formula (I) in water or an organic solvent, such as a ketone, alcohol or glycol ether. These solutions may contain a surface active agent (for example to improve water dilution or prevent crystallisation in a spray tank). 
     Emulsifiable concentrates (EC) or oil-in-water emulsions (EW) may be prepared by dissolving a compound of formula (I) in an organic solvent (optionally containing one or more wetting agents, one or more emulsifying agents or a mixture of said agents). Suitable organic solvents for use in ECs include aromatic hydrocarbons (such as alkylbenzenes or alkylnaphthalenes, exemplified by SOLVESSO 100, SOLVESSO 150 and SOLVESSO 200; SOLVESSO is a Registered Trade Mark), ketones (such as cyclohexanone or methylcyclohexanone) and alcohols (such as benzyl alcohol, furfuryl alcohol or butanol), N-alkylpyrrolidones (such as N-methylpyrrolidone or N-octylpyrrolidone), dimethyl amides of fatty acids (such as C 8 -C 10  fatty acid dimethylamide) and chlorinated hydrocarbons. An EC product may spontaneously emulsify on addition to water, to produce an emulsion with sufficient stability to allow spray application through appropriate equipment. Preparation of an EW involves obtaining a compound of formula (I) either as a liquid (if it is not a liquid at room temperature, it may be melted at a reasonable temperature, typically below 70° C.) or in solution (by dissolving it in an appropriate solvent) and then emulsifying the resultant liquid or solution into water containing one or more SFAs, under high shear, to produce an emulsion. Suitable solvents for use in EWs include vegetable oils, chlorinated hydrocarbons (such as chlorobenzenes), aromatic solvents (such as alkylbenzenes or alkylnaphthalenes) and other appropriate organic solvents which have a low solubility in water. In particularly preferred embodiments, compounds of formula I will be formulated as an EC or EW formulation. 
     Microemulsions (ME) may be prepared by mixing water with a blend of one or more solvents with one or more SFAs, to produce spontaneously a thermodynamically stable isotropic liquid formulation. A compound of formula (I) is present initially in either the water or the solvent/SFA blend. Suitable solvents for use in MEs include those hereinbefore described for use in in ECs or in EWs. An ME may be either an oil-in-water or a water-in-oil system (which system is present may be determined by conductivity measurements) and may be suitable for mixing water-soluble and oil-soluble pesticides in the same formulation. An ME is suitable for dilution into water, either remaining as a microemulsion or forming a conventional oil-in-water emulsion. 
     Suspension concentrates (SC) may comprise aqueous or non-aqueous suspensions of finely divided insoluble solid particles of a compound of formula (I). SCs may be prepared by ball or bead milling the solid compound of formula (I) in a suitable medium, optionally with one or more dispersing agents, to produce a fine particle suspension of the compound. One or more wetting agents may be included in the composition and a suspending agent may be included to reduce the rate at which the particles settle. Alternatively, a compound of formula (I) may be dry milled and added to water, containing agents hereinbefore described, to produce the desired end product. 
     Aerosol formulations comprise a compound of formula (I) and a suitable propellant (for example n-butane). A compound of formula (I) may also be dissolved or dispersed in a suitable medium (for example water or a water miscible liquid, such as n-propanol) to provide compositions for use in non-pressurised, hand-actuated spray pumps. 
     A compound of formula (I) may be mixed in the dry state with a pyrotechnic mixture to form a composition suitable for generating, in an enclosed space, a smoke containing the compound. 
     Capsule suspensions (CS) may be prepared in a manner similar to the preparation of EW formulations but with an additional polymerisation stage such that an aqueous dispersion of oil droplets is obtained, in which each oil droplet is encapsulated by a polymeric shell and contains a compound of formula (I) and, optionally, a carrier or diluent therefor. The polymeric shell may be produced by either an interfacial polycondensation reaction or by a coacervation procedure. The compositions may provide for controlled release of the compound of formula (I) and they may be used for seed treatment. A compound of formula (I) may also be formulated in a biodegradable polymeric matrix to provide a slow, controlled release of the compound. 
     A composition may include one or more additives to improve the biological performance of the composition (for example by improving wetting, retention or distribution on surfaces; resistance to rain on treated surfaces; or uptake or mobility of a compound of formula (I)). Such additives include surface active agents, spray additives based on oils, for example certain mineral oils or natural plant oils (such as soy bean and rape seed oil), and blends of these with other bio-enhancing adjuvants (ingredients which may aid or modify the action of a compound of formula (I)). 
     A compound of formula (I) may also be formulated for use as a seed treatment, for example as a powder composition, including a powder for dry seed treatment (DS), a water soluble powder (SS) or a water dispersible powder for slurry treatment (WS), or as a liquid composition, including a flowable concentrate (FS), a solution (LS) or a capsule suspension (CS). The preparations of DS, SS, WS, FS and LS compositions are very similar to those of, respectively, DP, SP, WP, SC and DC compositions described above. Compositions for treating seed may include an agent for assisting the adhesion of the composition to the seed (for example a mineral oil or a film-forming barrier). 
     Wetting agents, dispersing agents and emulsifying agents may be surface SFAs of the cationic, anionic, amphoteric or non-ionic type. 
     Suitable SFAs of the cationic type include quaternary ammonium compounds (for example cetyltrimethyl ammonium bromide), imidazolines and amine salts. 
     Suitable anionic SFAs include alkali metals salts of fatty acids, salts of aliphatic monoesters of sulphuric acid (for example sodium lauryl sulphate), salts of sulphonated aromatic compounds (for example sodium dodecylbenzenesulphonate, calcium dodecylbenzenesulphonate, butylnaphthalene sulphonate and mixtures of sodium di-isopropyl- and tri-isopropyl-naphthalene sulphonates), ether sulphates, alcohol ether sulphates (for example sodium laureth-3-sulphate), ether carboxylates (for example sodium laureth-3-carboxylate), phosphate esters (products from the reaction between one or more fatty alcohols and phosphoric acid (predominately mono-esters) or phosphorus pentoxide (predominately di-esters), for example the reaction between lauryl alcohol and tetraphosphoric acid; additionally these products may be ethoxylated), sulphosuccinamates, paraffin or olefine sulphonates, taurates and lignosulphonates. 
     Suitable SFAs of the amphoteric type include betaines, propionates and glycinates. 
     Suitable SFAs of the non-ionic type include condensation products of alkylene oxides, such as ethylene oxide, propylene oxide, butylene oxide or mixtures thereof, with fatty alcohols (such as oleyl alcohol or cetyl alcohol) or with alkylphenols (such as octylphenol, nonylphenol or octylcresol); partial esters derived from long chain fatty acids or hexitol anhydrides; condensation products of said partial esters with ethylene oxide; block polymers (comprising ethylene oxide and propylene oxide); alkanolamides; simple esters (for example fatty acid polyethylene glycol esters); amine oxides (for example lauryl dimethyl amine oxide); and lecithins. 
     Suitable suspending agents include hydrophilic colloids (such as polysaccharides, polyvinylpyrrolidone or sodium carboxymethylcellulose) and swelling clays (such as bentonite or attapulgite). 
     A compound of formula (I) may be applied by any of the known means of applying pesticidal compounds. For example, it may be applied, formulated or unformulated, to the pests or to a locus of the pests (such as a habitat of the pests, or a growing plant liable to infestation by the pests) or to any part of the plant, including the foliage, stems, branches or roots, to the seed before it is planted or to other media in which plants are growing or are to be planted (such as soil surrounding the roots, the soil generally, paddy water or hydroponic culture systems), directly or it may be sprayed on, dusted on, applied by dipping, applied as a cream or paste formulation, applied as a vapour or applied through distribution or incorporation of a composition (such as a granular composition or a composition packed in a water-soluble bag) in soil or an aqueous environment. 
     A compound of formula (I) may also be injected into plants or sprayed onto vegetation using electrodynamic spraying techniques or other low volume methods, or applied by land or aerial irrigation systems. 
     Compositions for use as aqueous preparations (aqueous solutions or dispersions) are generally supplied in the form of a concentrate containing a high proportion of the active ingredient, the concentrate being added to water before use. These concentrates, which may include DCs, SCs, ECs, EWs, MEs SGs, SPs, WPs, WGs and CSs, are often required to withstand storage for prolonged periods and, after such storage, to be capable of addition to water to form aqueous preparations which remain homogeneous for a sufficient time to enable them to be applied by conventional spray equipment. Such aqueous preparations may contain varying amounts of a compound of formula (I) (for example 0.0001 to 10%, by weight) depending upon the purpose for which they are to be used. 
     A compound of formula (I) may be used in mixtures with fertilisers (for example nitrogen-, potassium- or phosphorus-containing fertilisers). Suitable formulation types include granules of fertiliser. The mixtures suitably contain up to 25% by weight of the compound of formula (I). 
     The invention therefore also provides a fertiliser composition comprising a fertiliser and a compound of formula (I). 
     The compositions of this invention may contain other compounds having biological activity, for example micronutrients or compounds having fungicidal activity or which possess plant growth regulating, herbicidal, insecticidal, nematicidal or acaricidal activity. 
     The compound of formula (I) may be the sole active ingredient of the composition or it may be admixed with one or more additional active ingredients such as a pesticide, fungicide, synergist, herbicide or plant growth regulator where appropriate. An additional active ingredient may: provide a composition having a broader spectrum of activity or increased persistence at a locus; synergise the activity or complement the activity (for example by increasing the speed of effect or overcoming repellency) of the compound of formula (I); or help to overcome or prevent the development of resistance to individual components. The particular additional active ingredient will depend upon the intended utility of the composition. Examples of suitable pesticides include the following:

     An example of a rice selective herbicide which may be included is propanil. An example of a plant growth regulator for use in cotton is PIX™. 
     Some mixtures may comprise active ingredients which have significantly different physical, chemical or biological properties such that they do not easily lend themselves to the same conventional formulation type. In these circumstances other formulation types may be prepared. For example, where one active ingredient is a water insoluble solid and the other a water insoluble liquid, it may nevertheless be possible to disperse each active ingredient in the same continuous aqueous phase by dispersing the solid active ingredient as a suspension (using a preparation analogous to that of an SC) but dispersing the liquid active ingredient as an emulsion (using a preparation analogous to that of an EW). The resultant composition is a suspoemulsion (SE) formulation. 
     Various aspects and embodiments of the present invention will now be illustrated in more detail by way of example. It will be appreciated that modification of detail may be made with out departing from the scope of the invention. 
     For the avoidance of doubt, where a literary reference, patent application, or patent, is cited within the text of this application, the entire text of said citation is herein incorporated by reference.

The reaction mixture was acidified and extracted three times with diethylether that was discarded. The aqueous phase was treated with sodium hydroxide solution to pH 9 again and extracted twice with ethyl acetate. Crude 2-[1-(3,5-difluoro-phenoxy)-ethyl]-4,5-dihydro-1H-imidazole was obtained as a crystalline product. 
     D: 0.9 g (4.2 mMol) of the product obtained under C was dissolved in dichloromethane and treated in the presence of 0.49 g (4.8 mMol) triethylamine with 0.96 g (4.4 mMol) bis-tert.-butoxy carbonic acid anhydride. After 30 minutes stirring at room temperature the mixture was washed with water, evaporated to dryness and chromatographed on silica gel (eluent: 30% ethyl acetate in n-heptane).

The evaporated product was purified on silica gel (eluant: cyclohexane/ethylacetate 4:1) to give as an oil 1,2,5-trifluoro-3-methoxymethoxy-4-methyl-benzene;  1 H-NMR (CDCl 3 ): 6.61, m, 1H; 5.04, s, 2H; 3.38, s, 3H; 2.02, s, 3H. 
     B: 0.54 g (2.62 mMol) of the product obtained in A was heated in a mixture of conc. HCl (5 ml) and iso-propanol (5 ml) for half an hour at 75° C. The cooled mixture was alkalinised with NaOH and extracted at &gt;pH 12 with tert.-butylmethylether, that was discarded. The basic aqueous phase was acidified again and extracted with dichloromethane, dried and evaporated at 500 mbar at 40° C., to leave as an oil 2,3,5-tetrafluoro-6-methylphenol. 
     C: 0.84 g (5.2 mMol) of the product obtained in B and 0.93 g (5.7 mMol) methanesulfonic acid 1-cyano-propyl ester were heated then at refluxing temperature for 4 hours in the presence of 0.89 g (6.4 mMol) potassium carbonate in 10 ml acetonitrile. The product was extracted with tert.-butylmethylether and water at pH 12, dried and evaporated to dryness. The crude material was purified on silicagel (eluent: cyclo-hexane/ethylacetate 9:1) to give as an oil 2-(2,3,5-trifluoro-6-methyl-phenoxy)-butyronitrile;  1 H-NMR (CDCl 3 ): 6.62, m, 1H; 4.66, t, 1H; 2.01, s, 3H; 2.05, m, 2H; 1.13, t, 3H. 
     D: 50 mg (0.2 mMol) of product obtained in C was heated in the presence of 0.52 g (0.86 mMol) ethylendiamine and a spatula amount of Na 2 S 4  in 2 ml methanol for 3 hours to refluxing temperature. Then the product was extracted with 2N HCl and tert.-butylmethylether, and the organic phase was discarded. The aqueous phase was neutralized with 30% NaOH and extracted at pH 12 with dichloromethane, dried and evaporated. The crude material was purified by flash chromatography (eluant: cyclo-hexane/ethylacetate/triethylamine 5:5:1), to give pure 2[1-(2,3,5-trifluoro-6-methyl-phenoxy)-propyl]-4,5-dihydro-1H-imidazole (table 3, example 1.022); M.P. 99-101° C.;  1 H-NMR (CDCl 3 ): 6.64, m, 1H; 4.72, t, 1H; 3.68, m, 2H; 3.55, m, 2H; 2.13, s, 3H; 1.98, m, 2H; 1.04, t, 3H. 
     Example 5 
     This Example illustrates the pesticidal/insecticidal properties of compounds of formula (I). The compounds numbers are those of the characterising data tables. Tests against the following pests Heliothis virescens, Myzus persicae, and Tetranychus urticae were performed as described below: 
     5.1 Heliothis virescens (Tobacco budworm): 
     Eggs (0-24 h old) were placed in 24-well microtiter plate on artificial diet and treated with test solutions at an application rate of 200 ppm by pipetting. After an incubation period of 4 days, samples were checked for egg mortality, larval mortality, and growth regulation. 
     The following compounds gave at least 80% control of Heliothis virescens: I-2, 1.017, 1.023, 1.026. 
     5.2 Myzus persicae (Green peach aphid): 
     Sunflower leaf discs were placed on agar in a 24-well microtiter plate and sprayed with test solutions at an application rate of 200 ppm. After drying, the leaf discs were infested with an aphid population of mixed ages. After an incubation period of 6 DAT, samples were checked for mortality. 
     The following compounds gave at least 80% control of Myzus persicae: 1.002, I-2, 1.005, XIV-2, 1.008, 1.009, 1.010, XI-2, III-2, 1.015, 1.017, 1.021, 1.023, 1.024, 1.026, 1.028, 1.029, 1.030, 1.031, 1.032, 1.034. 
     5.3 Myzus persicae (Green peach aphid): 
     Roots of pea seedlings, infested with an aphid population of mixed ages, were placed directly in the test solutions of 24 ppm. 6 days after introduction, samples were checked for mortality. 
     The following compounds gave at least 80% control of Myzus persicae: I-2, XIV-2, 1.008, 1.009, 1.017, 1.018, 1.021, 1.023, 1.026, 1.028, 1.029, 1.030, 1.031, 1.032, 1.034.
