Derivatives of thiocarbamic acid. Part II. The formation of 1,2,4-triazole salts from amines and methyl dithiocarbazate. Some attempts to prepare substituted 1-thiocarbamoylthiocarbohydrazides

Abstract

Co-products of 4-substituted thiosemicarbazides in the reaction of amines with methyl dithiocarbazate have been isolated and identified as salts of 4-amino-3,5-dimercapto-1,2,4-triazole rather than the linear substituted 1-thiocarbamoylthiocarbohydrazides (A). The yield of salt could not be increased by using a tertiary amine. Although the substituted compounds (A) are more difficult to isolate than the parent substance, a benzylidene derivative was readily prepared.
