Abstract

Schiff bases (1a-1d) were synthesized by the condensation of 3-hydroxyquinoxaline-2-carboxaldehyde with 2-amino pyridine, 3-amino phenol, 2-amino benzoic acid, phenylalanine by an ecofriendly approach without using any organic solvents. The synthesized Schiff bases were confirmed on the basis of H1 NMR and IR spectroscopic analysis.
