Abstract
Microwave assisted synthesis and characterization of novel hydrazone derivatives
Author(s): Kavita, Pramila Joshi, Yogesh Chandra JoshiA simple and efficient method has been developed for the synthesis of Oalkyl alkyl-1-(4-substituted benzylidene) phosphonohydrazone derivatives (3a-j) using silica supported microwave irradiation technique under solvent free conditions. The series of phosphonohydrazone derivatives were synthesized by the condensation reaction of O-alkyl alkylphosphorohydrazides (1a-e) with substituted benzaldehydes. The synthesized compounds were structurally confirmed by elemental analysis, FT-IR, 1H NMR and mass spectroscopy.
