Description:
This is a continuation-in-part of application Ser. No. 012,925, filed 02/09/87 now abandoned. 
    
    
     This invention relates to a new class of 2,6-substituted pyridinecarboxylic acid derivatives having a wide range of activity as herbicides. 
     Pyridine derivatives have, for many years, been investigated for use in the biological sciences. For example, 2,6-bis-(trifluoromethyl)-4-pyridinols have been found useful as herbicides and fungicides as disclosed in U.S. Pat. No. 3,748,334. Such compounds are characterized by substitution in the 4-position by a hydroxy radical. In addition to the hydroxy radical, the pyridine nucleus may also be substituted with bromo, chloro or iodo radicals. Trifluoromethyl pyridine derivatives have also been disclosed in U.S. Pat. Nos. 2,516,402 and 3,705,170 wherein the nucleus is further substituted by halogens as well as numerous other substituents. Some of these compounds are also noted to be useful as herbicides. 
     Also known because of their fungicidal activity are 4-substituted 2,6-dichloro-3,5-dicyanopyridines wherein the 4-position is substituted with alkyl, phenyl, naphthyl or pyridyl groups. Such compounds are disclosed in U.S. Pat. No. 3,284,293, while similar compounds are disclosed in U.S. Pat. No. 3,629,270 wherein the 4-position is substituted with a heterocyclic group wherein the hetero atom is oxygen or sulfur. 
     In EPO patent 44,262 there are disclosed 2,6-dialkyl-3-phenylcarbamyl-5-pyridinecarboxylates and -5-cyano-compounds useful as herbicides. There is no disclosure of the 2-haloalkyl radicals nor any substitution in the 4-position of the pyridine ring. 
     The pyridine derivatives have also received attention in the search for new herbicides and have been reported in U.S. Pat. Nos. 1,944,412, 3,637,716, and 3,651,070. All of these patents disclose polyhalo derivatives of dicarboxypyridines. All have in common the direct substitution on a ring carbon by a halogen in the 3- and 5-positions while the 2- and 6-positions are occupied by carboxylate groups. The 4-position is open to substitution by a wide range of materials including halogens, hydroxy radicals, alkoxy, and carboxyl groups. Such compounds have found utilization as herbicides, bactericides, and fungicides. When the 4 position is occupied by a silver salt, U.S. Pat. No. 1,944,412 discloses that such compounds have been utilized in the production of X-ray pictures with intravenous injection of such compounds. 
     Pyridine dicarboxylate compounds useful as herbicides are described in European Patent publication No. 133,612 published Feb. 27, 1985 which corresponds to U.S. application Ser. No. 612,021. These compounds have fluorinated methyl groups at the 2- and 6-positions and carboxylic acid derivative at the 3- and 5-positions. 
     Other pyridine dicarboxylate compounds including pyrazole amides are disclosed in European Patent publication No. 0182769, published May 28, 1986. This European publication corresponds to U.S. application Ser. No. 768,659.

     DETAILED DESCRIPTION OF THE INVENTION 
     The compounds of this invention are readily prepared by reaction of a heterocyclic amine with the desired pyridinecarboxylic acid halide or pyridinedicarboxylic acid halide in the presence of a base (which may be an excess of the heterocyclic amine). Steps 1-9 which follow set out in detail the preparation of three specific acid halides which are used as starting materials for the compounds of this invention. Other acid halides may be readily prepared using the procedures of Steps 1-9 by varying the ketoester and aldehyde used in Step 1 to obtain the desired substituents in the pyridinedicarboxylate product. Other suitable pyridinedicarboxylate acid halides as starting materials are shown in European Patent publication No. 133,612 in Examples 44-51 and 82-83 inclusive. Other acid halide starting materials may be readily prepared using the techniques set out in that European Patent publication. 
     The following Steps 1-9 illustrate an example of the procedures for preparation of the acid halide compounds which are the starting materials for making the amides of the present invention. In these steps, a β-ketoester is reacted with an aldehyde to form a pyran (Step 1). The pyran is then reacted with ammonia to form a dihydroxypiperidine (Step 2), which is dehydrated to make a dihydropyridine compound (Step 3). The dihydropyridine is then oxidized or dehydrofluorinated to prepare a pyridinedicarboxylate compound (Step 4). 
     The ester groups of the pyridinedicarboxylate compound are the ester groups of the β-ketoester, and the 4-position of the pyridine is substituted with the same substituent as is on the aldehyde reagent. 
     When the pyridinedicarboxylate is substituted at the 2- or 6-position with a trifluoromethyl radical and at the other of these positions with a difluoromethyl radical, hydrolysis of the pyridine dicarboxylate compound occurs selectively on the side having the CF 2  H group when one equivalent of a base such as KOH is employed in the hydrolysis (Step 8). When two equivalents of base or more are employed, the dicarboxylate is hydrolyzed to the diacid (Step 5). The diacid may be converted to the diacid chloride by treatment with a chlorinating agent such as SOCl 2  or PCl 5 . Following this conversion, treatment with one equivalent of an alcohol selectively esterifies the diacid chloride on the chloride group adjacent the CF 2  H group.

     Step 3 Product may be Prepared in Better Overall Yield Without Isolation of Step 1 and Step 2 Product by the Following Procedure 
     To a mechanically stirred mixture of 340.3 g (1.98 mole) of 98.9% pure methyl trifluoroacetoacetate (MTFAA), 100 mL of toluene and 0.86 g (0.01 mol) of piperidine was added 90.5 g (1.03 mol) of isovaleraldehyde in 20 minutes. The reaction mixture exothermed causing a rise of temperature to 83° C. The reaction mixture was maintained at 80° C. for 3 hours.  19  F NMR showed that the reaction was 89% complete. Heat was removed, and the reaction mixture was diluted with 125 mL of toluene and stirred overnight (16 hours). Gaseous ammonia was passed through the reaction mixture, the exotherm caused a rise of temperature to 68° C. in 50 minutes. A water cooling bath was applied to the reaction vessel to reduce the reaction temperature to 53° C. while ammonia was passed continuously. A total of 47.3 g (2.78 mol) of ammonia was passed in 1.5 hours. The reaction mixture was diluted with 100 mL of toluene. A Claisen distillation head was attached to the reaction vessel. 
     Excess ammonia and parts of toluene were removed in vacuo (water aspirator) while temperature was maintained at 26° C. An additional 200 mL of toluene was added, and the distillation was continued to remove a total of 200 mL of distillate in 1.5 hours. The reaction mixture was diluted with 100 mL of toluene and cooled to 5° C. with an ice bath. Sulfuric acid (453 g, 4.53 mol) was added in 5 minutes. The exotherm caused the temperature to rise to 25° C. The temperature gradually subsided to 5° C. in 10 minutes and was maintained at 5° C. for 40 minutes. An additional 95 g (0.95 mol) of sulfuric acid was added, and the reaction mixture was stirred at 5° C. for 20 minutes before being poured into a mixture of 500 mL of toluene and 2 L of ice water. The toluene layer was separated and the aqueous layer was extracted once with 500 mL of toluene. The combined toluene extracts were washed successively with 500 mL of water, 500 mL of saturated aqueous NaHCO 3 , 500 mL of brine and concentrated in vacuo to 363.6 g of an oil. GC area percent analysis indicated that the oil contained 9% of 3,4-dihydropyridine isomer and 75.4% of 1,4-dihydropyridine isomer corresponding to an overall yield of 82.9% from MTFAA.

     PRE-EMERGENT HERBICIDE EXAMPLES 
     As noted above, compounds of this invention have been found to be effective as herbicides, particularly pre-emergent herbicides. Tables A and B summarize results of tests conducted to determine the pre-emergent herbicidal activity of the compounds of this invention. The herbicidal ratings used in Tables A and B were assigned according to a scale based on the percent inhibition of each plant species. The herbicide rating symbols in Tables A and B are defined as follows: 
     
         ______________________________________% Inhibition           Rating______________________________________ 0-24                  025-49                  150-74                  2 75-100                3Not planted            --Species planted, no data N or a blank______________________________________ 
    
     For some compounds of this invention data were orginally recorded as percent inhibition (or control) in ten percent increments. Where this system was used, the percentages have been mathematically converted to the above equivalent system using the correlation table above. 
     PRE-EMERGENT ACTIVITY ON WEEDS 
     One set of pre-emergent tests was conducted as follows: 
     Topsoil was placed in a pan and compacted to a depth of 0.95 to 1.27 cm. from the top of the pan. A predetermined number of seeds of each of several monocotyledonous and dicotyledonous annual plant species and/or vegetative propagules of various perennial plant species were placed on top of the soil. The soil required to level fill a pan after seeding or adding vegetative propagules was weighed into another pan. A known amount of the test compound dissolved or suspended in an organic solvent or water and applied in acetone or water as a carrier was thoroughly mixed with this cover soil, and the herbicide/soil mixture was used as a cover layer for the previously prepared pan. In Table A below the amount of active ingredient was equivalent to an application rate of 11.2 kg/ha. After treatment, the pans were moved to a greenhouse bench where they were watered as needed to give adequate moisture for germination and growth. 
     Approximately 10-14 days (usually 11 days) after planting and treating, the pans were observed and the results recorded. In some instances, a second observation was made approximately 24-28 days after seeding and treating, and these observations are indicated in the following tables by a &#34;pound&#34; (#) sign immediately following the Example number. 
     The plant species usually regarded as weeds which were utilized in one set of pre-emergent activity test, the data for which are shown in Table A, are identified by letter headings printed diagonally above the columns according to the following legend:

     PRE-EMERGENCE ACTIVITY ON WEEDS AND CROPS 
     In another set of tests, the pre-emergence activity of compounds of this invention was tested on weeds in the presence of crop plants. In these tests the following procedure was used: 
     Topsoil was sieved to pass through a 1/2 inch (1.27 cm) screen. Fertilizer was added to the topsoil in some of the tests, while in testing other compounds the fertilizer was omitted. The mixture was then sterilized by exposure to methyl bromide or by heating. 
     The topsoil mixture was placed in an aluminum pan and compacted to a depth of about 1.27 cm. from the top of the pan. A predetermined number of seeds of each of several monocotyledonous and dicotyledonous plant species and where noted vegetative propagules of various perennial plant species. The soil required to level fill a pan after seeding or adding vegetative propagules was weighed into another pan. A known amount of test compound was dissolved or suspended in acetone or a suitable organic solvent as a 1% solution or suspension and applied to the cover soil using a sprayer at the desired rate. The spray was thoroughly mixed with this cover soil, and the herbicide/soil mixture was used as a cover layer for the previously prepared pan. Untreated soil was used as a cover layer for control pans. Alternatively, the pans may be covered with the soil layer and the spray solution uniformly applied to the soil surface. When this latter method was used, the statement &#34;surface application&#34; accompanies the test data. In Table B below the amount of active ingredient applied is shown in the Table. After treatment, the pans were moved to a greenhouse bench. Moisture was supplied to each pan as needed for germination and growth. Growth of each species was observed and corrective measures (greenhouse fumigation, insecticide treatment, and the like) were applied as needed 
     Approximately 10-14 days (usually 11 days) after planting and treating, the pans were observed and the results recorded. In some instances, a second observation is made (usually 24-28 days after seeding and treating, although this time interval was at the discretion of the observer), and these observations are indicated in the following tables by a &#34;pound&#34; sign (#) immediately following the Example number. 
     The pre-emergence data for weeds in the presence of crop plants is shown in the following Table B. In these tests, the plants are identified according to the following column headings printed diagonally above each column, the first column being the rate of application of the test compound in kg/ha:

     POST-EMERGENT HERBICIDE EXAMPLES 
     Although as has been stated above the compounds of this invention exhibit predominantly pre-emergence activity in greenhouse testing, nevertheless many of these compounds are active post-emergent herbicides. The post-emergent activity is best seen on younger plants treated at the 11/2 to 2 leaf stage. In most of the tests which follow, larger and more developed plants were used. 
     The post-emergence herbicidal activity of compounds of this invention was demonstrated by greenhouse testing, and the results are shown in the following Table C. The post-emergent herbicidal activity index used in Table C is as follows: 
     
         ______________________________________Plant Response    Index______________________________________ 0-24% inhibition 025-49% inhibition 150-74% inhibition 275-99% inhibition 3100% inhibition   4Species not planted             -- or a blankSpecies planted, no data             N______________________________________ 
    
     As was the case with the pre-emergence data, some of the compounds initially received ratings for plant response directly as percent inhibition in ten percent increments. Where this is the case, the percentage has been converted according to the scale above. 
     POST-EMERGENCE ACTIVITY ON WEEDS 
     Topsoil was placed in pans having holes in the bottom and compacted to a depth of 0.95 to 1.27 cm. from the top of the pan. A predetermined number of seeds of each of several dicotyledonous and monocotyledonous annual plant species and/or vegetative propagules for the perennial plant species were placed on the soil and pressed into the soil surface. The seeds and/or vegetative propagules were covered with soil and leveled. The pans were then placed on a bench in the greenhouse and watered as needed for germination and growth. After the plants reached the desired age (two to three weeks), each pan (except the control pans) was removed to a spraying chamber and sprayed by means of an atomizer. The spray solution or suspension contained about 0.4% by volume of an emulsifying agent and a sufficient amount of the candidate chemical to give an application rate of the active ingredient of 11.2 kg/ha while applying a total amount of solution or suspension equivalent to 1870 L/Ha (200 gallons/acre). The pans were returned to the greenhouse and watered as before and the injury to the plants as compared to those in control pans was observed at approximately 10-14 days (usually 11 days) and in some instances observed again at 24-28 days (usually 25 days) after spraying. These latter observations are designated by a &#34;pound&#34; sign (#) following the column of example numbers in the Table. The plant species used in this set of tests were the same as those used in the first set of pre-emergence tests, and the plant identifying codes are the same as those shown for Table A.

     POST-EMERGENCE ACTIVITY ON WEEDS AND CROPS 
     Compounds of this invention were tested for herbicidal activity on weed plants in the presence of crop plants according to the following procedure: 
     Topsoil (silt loam) is sieved through a screen having 1.27 cm openings. In some of the tests the soil was mixed with fertilizer (1225 g/cm. m of 12/5/9 containing isobutylidene diurea), while in other tests the fertilizer was omitted. This mixture is steam sterilized and then placed in aluminum pans 6.985 cm deep having ten holes in the bottom each 0.635 cm in diameter. The soil mixture is compacted to a depth of 1.27 cm. from the top of the pan. A predetermined number of seeds of each of several dicotyledonous and monocotyledonous annual plant species and/or vegetative propagules for the perennial plant species are placed on the soil and pressed into the soil surface. The seeds and/or vegetative propagules are covered with 1.27 cm of a mixture of 50% topsoil and 50% of a mixture of Canadian sphagnum peat moss, vermiculite and a wetting agent. The pans are then placed on a capillary mat on a greenhouse bench and subirrigated as needed. After the plants reach the desired stage, each pan (except the control pans) is removed to a spraying chamber and sprayed by means of an atomizer, operating at a spary pressure of 170.3 kPa (10 psig) at the application rates noted in Table D. In the spray solution is an amount of an emulsifying agent mixture (35% butylamine salt of dodecylbenzenesulfonic acid and 65% tall oil condensed with ethylene oxide in the ratio of 11 mols of ethylene oxide/mol of tall oil) to give a spray solution or suspension. The spray solution or suspension contains a sufficient amount of the candidate chemical in order to give application rates of the active ingredient corresponding to those shown in Table D below while applying a total amount of solution or suspension equivalent to 1870 L/Ha (200 gallons/acre). The pans are returned to the greenhouse and watered as before and the injury to the plants as compared to the control pans is observed at approximately 10-14 days (usually 11 days) and in some instances observed again at 24-28 days (usually 25 days) after spraying. These latter observations are designated by a &#34;pound&#34; sign (#) following the column of example numbers in the Table. 
     In the following Table D the legends used to identify the plant species are the same as those used in the preceding Table B.

     From these data, it can be seen that compounds claimed herein have activity which is markedly superior to closely related compounds, and that some are substantially equal to the prior art compound of Example 47. 
     The herbicidal compositions of this invention, including concentrates which require dilution prior to application, may contain at least one active ingredient and an adjuvant in liquid or solid form. The compositions are prepared by admixing the active ingredient with an adjuvant including diluents, extenders, carriers, and conditioning agents to provide compositions in the form of finely-divided particulate solids, granules, pellets, solutions, dispersions or emulsions. Thus, it is believed that the active ingredient could be used with an adjuvant such as a finely-divided solid, a liquid of organic origin, water, a wetting agent, a dispersing agent, an emulsifying agent or any suitable combination of these. 
     Suitable wetting agents are believed to include alkyl benzene and alkyl naphthalene sulfonates, sulfated fatty alcohols, amines or acid amides, long chain acid esters of sodium isothionate, esters of sodium sulfosuccinate, sulfated or sulfonated fatty acid esters, petroleum sulfonates, sulfonated vegetable oils, ditertiary acetylenic glycols, polyoxyethylene derivatives of alkylphenols (particularly isooctylphenol and nonylphenol) and polyoxyethylene derivatives of the mono-higher fatty acid esters of hexitol anhydrides (e.g., sorbitan). Preferred dispersants are methyl, cellulose, polyvinyl alcohol, sodium lignin sulfonates, polymeric alkyl naphthalene sulfonates, sodium naphthalene sulfonate, and polymethylene bisnaphthalene sulfonate. 
     Wettable powders are water-dispersible compositions containing one or more active ingredients, an inert solid extender and one or more wetting and dispersing agents. The inert solid extenders are usually of mineral origin such as the natural clays, diatomaceous earth and synthetic minerals derived from silica and the like. Examples of such extenders include kaolinites, attapulgite clay and synthetic magnesium silicate. The wettable powders compositions of this invention usually contain from above 0.5 to 60 parts (preferably from 5-20 parts) of active ingredient, from about 0.25 to 25 parts (preferably 1-15 parts) of wetting agent, from about 0.25 to 25 parts (preferably 1.0-15 parts) of dispersant and from 5 to about 95 parts (preferably 5-50 parts) of inert solid extender, all parts being by weight of the total composition. Where required, from about 0.1 to 2.0 parts of the solid inert extender can be replaced by a corrosion inhibitor or anti-foaming agent or both. 
     Other formulations include dust concentrates comprising from 0.1 to 60% by weight of the active ingredient on a suitable extender; these dusts may be diluted for application at concentrations within the range of from about 0.1-10% by weight. 
     Aqueous suspensions or emulsions may be prepared by stirring a nonaqueous solution of a water-insoluble active ingredient and an emulsification agent with water until uniform and then homogenizing to give stable emulsion of very finely-divided particles. The resulting concentrated aqueous suspension is characterized by its extremely small particle size, so that when diluted and sprayed, coverage is very uniform. Suitable concentrations of these formulations contain from about 0.1-60% preferably 5-50% by weight of active ingredient, the upper limit being determined by the solubility limit of active ingredient in the solvent. 
     Concentrates are usually solutions of active ingredient in water-immiscible or partially water-immiscible solvents together with a surface active agent. Suitable solvents for the active ingredient of this invention include dimethylformamide, dimethylsulfoxide, N-methyl-pyrrolidone, hydrocarbons, and water-immiscible ethers, esters, or ketones. However, other high strength liquid concentrates may be formulated by dissolving the active ingredient in a solvent then diluting, e.g., with kerosene, to spray concentration. 
     The concentrate compositions herein generally contain from about 0.1 to 95 parts (preferably 5-60 parts) active ingredient, about 0.25 to 50 parts (preferably 1-25 parts) surface active agent and where required about 4 to 94 parts solvent, all parts being by weight based on the total weight of emulsifiable oil. 
     Granules are physically stable particulate compositions comprising active ingredient adhering to or distributed through a basic matrix of an inert, finely-divided particulate extender. In order to aid leaching of the active ingredient from the particulate, a surface active agent such as those listed hereinbefore can be present in the composition. Natural clays, pyrophyllites, illite, and vermiculite are examples of operable classes of particulate mineral extenders. The preferred extenders are the porous, absorptive, preformed particules such as preformed and screened particulate attapulgite or heat expanded, particulate vermiculite and the finely-divided clays such as kaolin clays, hydrated attapulgite or bentonitic clays.

     When operating in accordance with the present invention, effective amounts of the compounds of this invention are applied to the soil containing the seeds, or vegetative propagules or may be incorporated into the soil media in any convenient fashion. The application of liquid and particulate solid compositions to the soil can be carried out by conventional methods, e.g., power dusters, boom and hand sprayers and spray dusters. The compositions can also be applied from airplanes as a dust or a spray because of their effectiveness at low dosages. 
     The exact amount of active ingredient to be employed is dependent upon various factors, including the plant species and stage of development thereof, the type and condition of soil, the amount of rainfall and the specific compounds employed. In selective preemergence application or to the soil, a dosage of from about 0.02 to about 11.2 kg/ha, preferably from about 0.1 to about 5.60 kg/ha, is usually employed. lower or higher rates may be required in some instances. One skilled in the art can readily determine from this specification, including the above examples, the optimum rate to be applied in any particular case. 
     The term &#34;soil&#34; is employed in its broadest sense to be inclusive of all conventional &#34;soils&#34; as defined in Webster&#39;s New International Dictionary, Second Edition, Unabridged (1961). Thus, the term refers to any substance or media in which vegetation may take root and grow, and includes not only earth but also compost, manure, muck, humus, sand, and the like, adapted to support plant growth. 
     Although the invention is described with respect to specific modifications, the details thereof are not to be construed as limitations.
