An Expedient Method for the Synthesis of Thiosemicarbazones under Microwave Irradiation in Solvent‐free Medium

Abstract

A simple, efficient and eco‐friendly method for the synthesis of thiosemicarbazones from thiosemicarbazides and aldehyde under microwave irradiation has been reported, and no solvent and catalyst were used. And the technique of microwave irradiation coupled with solvent‐free condition proved to be a quite valuable method in the organic synthesis.

Schiff Bases and their Copper(II) Complexes Derived from Cinnamaldehyde and Different Hydrazides: Synthesis and Antibacterial Properties

“…The purity of the synthesised L 1 , L 2 , and L 3 was also confirmed using FTIR spectroscopy and the stretching band within 1,445 cm −1 to 1,491 cm −1 region is contributed by the stretching band of C− −N, υ C− −N , that is common for hydrazones [29]. Broad and medium bands between 3,500 cm −1 and 3,200 cm −1 , containing an N-H stretching band was evident in the spectra while in the range between 1,646 cm −1 and 1,670 cm −1 , a prominent stretching band for C− −O double bond from carbonyl group was identified.…”
