Description:
FIELD OF THE INVENTION 
       [0001]    This invention relates to novel neonicotinoid derivatives, the preparation method and the uses thereof. 
       BACKGROUND OF THE INVENTION 
       [0002]    Represented by Imidacloprid, neonicotinoid insecticide has been act as a hot area of pesticide discovery, with the character of high insecticidal activity, wide insecticidal spectrum, low toxic to mammals and aquatic animals, good systematic properties, appropriate field stability and environmental friendship. After Imidacloprid, a series of neonicotinoid insecticides such as Thiacloprid, Clothianidin, Thiamethoxam, Acetamiprid, Nitenpyram and Dinotefuran were developed (EP 247477, 296453, 685477, 235725, 235725, 315826, 192060, 244777, 0386565, 580553, 1031566, JP 62292765, 8259568, 8291171 and 7242633). 
         [0003]    However, the application and development of these compounds are limited due to the resistance caused by over frequent use of Imidacloprid and cross-resistance among neonicotinoid insecticides caused by structural similarity. Meanwhile, the neonicotinoid insecticides mainly show high activity to Homoptera and Coleoptera pests, and the narrow insecticidal spectrum limits their broad application in pest control. 
         [0004]    Therefore, it is urgent in the art to develop compounds with efficient activities from high active nitromethylene compounds so as to solve the problem of resistance, enlarge the insecticidal spectrum and apply them in insecticide compositions.

The invented active compounds can be prepared into the conventional formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols, natural and synthetic materials impregnated with active compounds, and micro-capsules in polymers, the coating complex for seed, preparations used with a combustion device (such as smoking cylindrantherae, smoking can and smoking plate) and ULV cold mist and warm mist preparations. 
         [0089]    These formulations may be produced in a known manner, for example, by mixing the active compounds with extenders, which are liquid or liquefied gaseous, solid diluents or carriers, optionally with the use of surface-active agents, which is emulsifying agents and/or dispersing agents, and/or foam-forming agents. In the case of using water as an extender, organic solvents can also be used as auxiliary solvents. 
         [0090]    It is generally proper to use liquid solvents as a diluent or carrier, for example, aromatic hydrocarbons, such as xylene, toluene and alkyl naphthalenes; chlorinated aromatic or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes and methylene chloride; aliphatic hydrocarbons, such as cyclohexane or paraffins, for example, mineral oil fractions; alcohols, such as ethanol or glycol as well as their ethers and esters; ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone; or uncommon polar solvents, such as dimethylformamide and dimethylsulfoxide, as well as water. By liquefied gaseous diluents or carriers are meant liquids which are gaseous at normal temperature under normal pressure, for example, aerosol propellants, such as halogenated hydrocarbons as well as butane, propane, nitrogen and carbon dioxide. 
         [0091]    The solid carrier comprises ground natural minerals, such as kaolins, clays, talcs, quartzs, attapulgites, montmorillonites or kieselguhrs; ground synthetic minerals, such as high dispersed silicic acid, alumina and silicate. The solid carrier used for particles is crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic coarse powder, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks and the like. 
         [0092]    Nonionic and anionic emulsifiers may be used as emulsifying and/or foam-forming agents, such as polyoxyethylene-fatty acid esters, polyoxyethylene-fatty alcohol ethers, for example, alkylaryl polyglycol ethers, alkylsulfonates, alkylsulfates, arylsulfonates as well as albumin hydrolysis products. Dispersing agents include, for example, lignin sulfite waste liquors and methyl cellulose. 
         [0093]    Adhesives such as carboxymethyl cellulose and natural and synthetic polymers, (such as gum arabic, polyvinyl alcohol and polyvinyl acetate) in the form of powders, granules or emulsions can be used in the formulations. It is possible to use colorants such as inorganic dyestuffs, for example, iron oxide, cobalt oxide and Prussian Blue, and organic dyestuffs, such as diazo dyestuffs or metal phthalo-cyanine dyestuffs, and trace nutritional agent, such as the salts of iron, manganese, boron, copper, cobalt, aluminum and zinc. 
         [0094]    The active compound of the invention can be present as a mixture with other active compounds in a commercial formulation or a use form prepared from the commercial formulation. The other compounds can be insecticide, bactericide, acaricide, nematocide, fungicide, growth controller and the like. The insecticide includes, e.g., phosphates, carbamate, pyrethroids, chlorinated hydrocarbons, benzoylurea, nereistoxin and material produced by microbion such as avermectin. 
         [0095]    Furthermore, the active compound of the invention can be present as a mixture with a synergist in a commercial formulation or a. use form prepared from the commercial formulation. Synergist is used to enhance the action of active compound, as the compound itself is active it is optional to use the synergist. 
         [0096]    Generally, the formulations contain 0.001-99.99 wt %, preferably 0.01-99.9 wt %, and more preferably 0.05-90 wt % of the active compound of invention. The concentration of the active compound in the use form prepared from the commercial formulation can vary within a wide range. The active compound concentration of the formulation for use is, for example, 0.0000001-100% (g/v), and preferably 0.0001- 1%.

     Insecticidal Activity Test of the Invented Compounds 
     (1) Activity Test for Cowpea Aphids ( Aphis Craccivoral ) 
       [0147]    Aphis, which belongs to Homoptera and has a piercing-sucking mouthpart, is a common insect for agricultural plant.  Aphis craccivoral  was tested by the way of immersing. 
         [0148]    Test method: exactly weighed various samples were independently added to N,N-dimethylformamide to form a 10 g/L stock solution. The mixture was diluted with 0.2 mL/L aqueous Triton X-100 solution to a concentration of 500 ppm After stably sucking on bean sprout, the adult aphis without wings together with bean sprout was dipped into 500 ppm dilution, taken out after 5 seconds, and the excess dilution was sucked out with bibulous paper and the adult aphis without wings was incubated in clean vessel at a constant temperature of 23° C. Each concentration was repeated for 3 times and the control group contained 0.2 mL/L aqueous Triton X-100 solution. The number of killed aphis was counted after 24 hours to calculate the mortality by the following formula: 
         [0000]      mortality(%)=(control alive aphis−treated alive aphis)/control alive aphis×100%.

       Example 15   
     Preparation of Insecticidal Composition Containing the Invented Active Compound 
       [0154]    (a) Oily Suspension 
         [0155]    The following components were prepared: 25 wt % of any compound selected from compounds 1-73; 5 wt % polyoxyethylene sorbital hexaoleate and 70 wt % higher aliphatic hydrocarbon oil. All of the components were ground in a sand mill until the solid granules were reduced to less than about 5 micrometer. The resultant viscous suspension could be used directly or may be used after it was emulsified in water. 
         [0156]    (b) Aqueous Suspension 
         [0157]    The following components were prepared: 25 wt % of any compound selected from compounds 1-73; 3 wt % hydrate attapulagit; 10 wt % calcium lignosulphonate; 0.5 wt % sodium dihydrogen phosphate and 61.5 wt % water. All of the components were ground in a ball mill until the solid granules were reduced to less than about 10 micrometer. The aqueous suspension could be used directly. 
         [0158]    (c) Bait Formulation 
         [0159]    The following components were prepared: 0.1-10 wt % of any compound selected from compounds 1-73; 80 wt % wheat flour and 19.9-10 wt % molasses. All of the components were sufficiently mixed and shaped according to the need. The edible bait could be oral ingested or distributed to domestic or industrial places such as kitchen, hospital, store and outdoor area infected by public health insects.
