Abstract

Azo dyes are extremely important in variety of industries for variety of technical purposes. Hence, a series of naphtholic azo dyes 1-9 were synthesized via diazotization of substituted aniline derivatives followed by azo coupling with 2-naphthol. In similar manner, diazotization followed by azo coupling with phenol afforded phenolic azo dyes 10-17 in excellent yields. The chemical structures of all synthesized compounds were confirmed using analytical data and spectroscopic technique which include Uv-visible, IR, Mass spectra, 1H- and 13C-NMR.
