Some aryl hydrazide derivatives have been synthesized including 1-(3-chloro-4-nitrophenyl)-2-(3-substituted benzylidene) hydrazines by FeCl 3 /Bentonite catalyzed solvent-free condensation of substituted phenyl hydrazine and aldehydes under microwave irradiation. The yields of the hydrazides are more than 70%. The synthesized hydrazides are characterized by the physical constants, micro analysis and spectroscopic data. Effect of catalyst, solvent effect substituent effect and optimization of the catalyst was studied by the percentage of isolated yields. From the catalyst optimization, the present study catalyst gave the better yield of products. The antimicrobial activities of all synthesized of 1-(3-chloro-4-nitrophenyl)-2-(3-substituted benzylidene) hydrazines have been evaluated using Bauer-Kirby disc diffusion method.
