摘要:
According to a novel process, triazolinethione derivatives of the formula in which R1 and R2 are each as defined in the description, can be prepared by a) reacting hydrazine derivatives of the formula with formaldehyde and thiocyanate of the formula X—SCN (III), in which X represents sodium, potassium or ammonium, in the presence of a diluent and if appropriate in the presence of an acid, and b) reacting the resulting triazolidinethiones of the formula either &agr;) with oxidizing agents, if appropriate in the presence of a catalyst and in the presence of a diluent, or &bgr;) with formic acid. The triazolidinethiones of the formula (IV) are novel.
