METHOD FOR PRODUCING TRIAZOLINETHIONE DERIVATIVES

摘要

The invention relates to a new method for producing triazolinethione derivatives of formula (I), in which R<1> and R<2> have the meanings given in the description. The method consists of a) reacting the hydrazine derivatives of formula (II) with carbonyl compounds of formula (III), in which R<3> and R<4> have the meanings given in the description, with potassium-, sodium- or ammonium thiocyanate, optionally in the presence of a diluent and/or an acid; and b) reacting the triazolidinethione derivatives of formula (V) thus produced with formic acid, optionally in the presence of a catalyst and/or a diluent. These triazolidinethione derivatives of formula (V) are new compounds.
