Abstract

A novel and efficient one-pot method has been developed for the synthesis of 2-amino-1,3,4-thiadiazoles using various carboxylic acid hydrazides with trimethylsilyl isothiocyanate (TMSNCS). In situ preparation of various thiosemicarbazides by the reaction of different carboxylic acid hydrazides with trimethylsilyl isothiocyanate (TMSNCS), followed by cyclodehydration of thiosemicarbazides under acidic conditions gave 2-amino-1,3,4-thiadiazoles in high yields (71-87%).
