An Investigation of C-13-NMR Spectra of Some Intramolecular Hydrogen Bonded and Non-Bonded Azo Dyes

Abstract

The C-13-NMR spectra of the azo dyes which were synthesized by reacting substituted benzenediazonium chloride with derivatives of some phenol have been measured. The spectral data of these compounds were described considering intramolecular hydrogen bond and not. The chemical shift assignments were made regarding substituent effects.
