发明名称 Method for producing triazolinthion derivatives
摘要 The invention relates to a novel method for producing triazolinthion derivatives of formula (I) in which R 1 and R 2 have the meanings given in the description. To this end, a) Hydrazine derivatives of formula (II) or addition salts thereof are reacted with an inorganic or organic acid with thiocyanate of formula (III) Y-SCN in which Y represents sodium, potassium or ammonium, said reaction is carried out in the presence of a diluting agent and optionally in the presence of a catalyst; b) the formed thiosemicarbazide derivatives of formula (IV) are reacted with formic acid optionally in the presence of a catalyst and optionally in the presence of a diluting agent. The thiosemicarbazide derivatives of formula (IV) are novel.
