Synthesis and Characterization of Chiral Nitrobenzaldehyde - Schiff Base Ligands

Abstract

Three chiral nitrobenzaldehyde/Schiff base ligands (2a-c) were prepared by the reaction of ortho, meta, and para-NO2 substituted benzaldehydes (1a-c) with (1R,2R)-(-)-1,2-diaminocyclohexane. The structures of ligands 2a-c were characterized by IR, 1H-NMR, 13C-NMR and elemental analysis.
