    (54) METHOD FOR OBTAINING 1,3,4-THIADIAZOL-2-KAPBOHOBOn ACID DERIVATIVES The invention relates to a method for producing new 1,3,4-thiadiazole-2-carboxylic acid derivatives with fungicidal and nematocidal action. A known method of oxidation of thioethers to sulfoxides or sulfones. The calculated amount of hydrogen peroxide in glacial acetic acid can be used as the oxidizing agent. Potassium permanganate in a solution of acetic or sulfuric acid 1 is used as an oxidizing agent along with hydrogen peroxide. The purpose of the invention is to obtain new 1,3,4-thiadiazole derivatives with chain properties. This goal is achieved by the fact that in the method of obtaining derivatives of 1,3,4-thiadiazole-2-carboxy acid of the general formula N-- (0), where R is (, -alkyl, C-C-alkenyl, (, -alkynyl or C (-C (, - cyclo-alkyl); R-C-C-alkoxycarbonyl, amio carbonyl, cetyl-4-cd-alkylaminocarbonyl, C-C-cycloalkyllag Shnocarbonyl, di-C-Cd-alkylaminocarbonyl, cyclohexylmethylaminocarbonyl, alkoxyalkylaminocarbonyl, alkyloxycarbonyl , piperidinocarbonyl or cyan; n is the number 1 or 2, the compound of the general formula WN, where R. and R have the above values, is subjected to mutual It can be used with hydrogen peroxide or potassium permagnate in equimolar amounts in acetic acid at temperatures from 0 to 120 ° C. The proposed compounds can be used alone or in conjunction with other biologically active substances. Other fungicides, nematocides, insecticides, or can be added. other means to combat agricultural pests, depending on the desired purpose. Biologically active substances are expediently used in the form of specially prepared mixtures such as, for example, powders, dispersing agents, granules, solutions / emulsions or suspensions, with the addition of liquid and / or solid carriers or, respectively, diluents, and under certain conditions - also surfactants. Suitable liquid carriers are water, mineral oils, or other organic solvent, for example, xylene, chlorobenzene, cyclohexanol, dioxane, acetonitrile, ethyl acetate, ethyl acetate, dimethylformamide, isophorone, and dimethylsulfoxyl. Lime, kaolin, chalk, tal attapulgite, other types of clay, as well as silica gel of natural or synthetic origin are used as solid carriers. Among surfactants, for example, salts of lignosulfonic acids, salts of alkyl benzoic sulfates, sulfates of amides and their acids, salts, ethoxylated amines and alcohols should be mentioned. If biologically active substances are used for pickling seed, it is possible to add coloring agents to provide clearly visible coloring of the pickled seeds. The proportion of the biologically active substance or the same substances in the composition of the means for their use may vary within wide limits. Accurate Concentration. biologically active substance depends mainly on its applied amount. Means Soderisite about 1 to 95 wt.%, Preferably from 20 to 50 wt.%, Biologically active substances. Accordingly, the proportion of liquid or solid carrier is about 99 to 5 wt.%. Under certain conditions, up to another 20% by weight of surfactant BET, ecTB is added. Depositing is possible in the usual way, for example by spraying, applying liquid in the form of chalk, dropping fog or mist, dusting, gassing, -, smoke, dispersion, dousing, or by milling with beer. In order to isolate the obtained new compounds, the distillation of the applied solvent under normal or reduced pressure or precipitation is used in the final stage of the synthesis; by diluting with water, preferably, from an organic solvent of low volatility such as diethyl ether; crystallization is also used.
