Spectroscopic studies of Schiff bases of 2,2?-dihydroxybiphenyl-3-carbaldehyde and para substituted anilines

Five Schiff bases derivatives of 2,2?-dihydroxybiphenyl-3-carboxaldehyde and various para substituted anilines have been synthesised and studied by FT-IR, 1H, 13C, 15N NMR and CPMAS spectroscopy. The structure of the Schiff base includes two intramolecular OH?O and OH?N hydrogen bonds forming a hydrogen-bonded chain. All Schiff bases studied exist in imine form in chloroform and acetonitrile solution. On the basis of the CPMAS and FT-IR spectra in solid state the SCH5 base has been proved to exist in the enamine form. ? 2003 Elsevier Science B.V. All rights reserved.
