Eco-friendly Synthesis, Spectral Correlation Analysis, and Antimicrobial Activities of Substituted (E)-1-benzylidene-2-(3-nitrophenyl)hydrazines

Orbital: The Electronic Journal of Chemistry, 2016
In the present study, a series of ten substituted (E)-1-benzylidene-2-(3-nitrophenyl)hydrazine compounds have been synthesized by condensation of  3-nitrophenylhydrazine with various substituted benzaldehydes using SiO2-H3PO4 catalyst under solvent free
