摘要：

The synthesis of new azoic-dyes containing aryloxytetrazole functional group is reported. The 5-(4'-aminophenoxy)tetrazole was diazotized and coupled with the electron rich aromatic rings. All dyes were characterized by H-1-NMR, C-13-NMR, IR, and UV-vis spectroscopies. They all decomposed above 174 degreesC except dye derived from 4-nitrophenol, which released nitrogen at 86 degreesC to produce tar. These dyes are yellow, brown, or red in color. All dyes are soluble in basic media. The imidoyl azide derivative of dye derived from beta-naphthol produced unexpected hydroxylamine derivative in refluxing 1,4-dioxane.
