Rapid Synthesis of 1,4-Diaryl Thiosemicarbazides using Microwave Technology

Abstract

A new and rapid method for the preparation of 1,4-diaryl thiosemicarbazides is reported. Ten 1,4-diaryl thiosemicarbazides have been synthesised in excellent yields (89.8–96.3%). The reaction proves to be extremely simple and highly efficient (in 1.5-5 min).
