| dc.description.abstract | The condensation of salicylaldehyde, o-vanillin, p-vanillin or vanillin with aniline or 1-aminonaphthalene had been used to produce variously substituted hydroxybenzaldimines .The compounds were characterized using 1 13 elemental analyses, FT-IR, UV-vis, HNMR and CNMR.The effects of the replacement of aniline with aminonaphthalene on the vibrational and electronic properties were report ed. The spectroscopic methods were used to confirm the tautomeric nature of the 2-OH or 4-OH substituted hydroxybenzaldimines which showed that most of the Schiff bases existed predominantly as enol-imine tautomer. The various spectroscopic techniques of the compounds were found useful in understanding the degree of stabilization of the tautomeric nature of the Schiff bases. It was observed that the variously substituted substituent and the type of solvent used for the spectroscopic examination determined the existence of intra or intermolecular hydrogen bonding, hence the formation of tautomer | en_US |
