| abstract |
The invention relates to a new method for producing triazolinethione derivatives of formula (I), in which R?1 and R2¿ 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 R4¿ 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. |
