Synthesis, spectroscopic studies of new azo ligands Schiff base and amines derived of 5-phenylazo-2-hydroxybenzaldehyde

Abstract

Three new azoimine ligands, namely bis[5-phenylazo-2-hydroxybenzaldehyde]-4,4′-diiminophenyl ether(1), bis[5-phenylazo-2-hydroxy benzaldehyde]-4,4′-diiminophenyl methane(2), bis[5-phenylazo-2-hydroxybenz aldehyde]-4,4′-diiminophenyl ethane(3) and their reduced imine form bis[5-phenylazo-2-hydroxybenz aldehyde]-4,4′-diaminophenyl ether(4), bis[5-phenylazo-2-hydroxybenzaldehyde]-4,4′-diaminophenyl methane (5), bis[5-phenylazo-2-hydroxybenzaldehyde]-4,4′-diaminophenyl ethane(6) were synthesized by reducing the imine groups of the azoimine (1-3) with Sodium borohydride. The azoimine (1-3) and their reduced form (4-6) were characterized using elemental analyses, IR, UV-Visible spectroscopy, 1H NMR, 13C NMR and mass spectra.
