摘要

Procedure for obtaining a selective thiocarbamate-based herbicidal composition characterized in that it comprises: in a first step, 2,3-dibromopropionitrile chloride is reacted with an amine of general formula: ** (Formula) ** in which R1 is hydrogen, alkenyl, or lower alkyl and R2 is alkyl, alkenyl, alkynyl, dimethoxyethyl, or 1-ethynyl-cyclohexyl, in the presence of a suitable solvent, at a temperature of about -20 to 0ºC and, upon completion of addition of the reagents, The reaction mixture is heated to a temperature of between about 50-60ºC, optionally with excess amine.
