Abstract:
A process for preparing a triazolinethione derivative of the formula (I) ##STR20##in whichR.sup.1 and R.sup.2 are identical or different and each represents optionally substituted alkyl, optionally substituted alkenyl, optionally substituted cycloalkyl, optionally substituted aralkyl, optionally substituted aralkenyl, optionally substituted aroxyalkyl, optionally substituted aryl or optionally substituted heteroaryl,comprisinga) in a first step, reacting a hydrazine derivative of the formula ##STR21##in whichR.sup.1 and R.sup.2 are each as defined above,or an addition salt thereof with an inorganic or organic acid,with a thiocyanate of the formulaY--SCN (III)in whichY represents sodium, potassium or ammonium,in the presence of a diluent, andb) reacting the resulting thiosemicarbazide derivative of the formula ##STR22##in whichR.sup.1 and R.sup.2 are each as defined abovewith formic acid.
