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 1 H-NMR, 1 3 C-NMR, IR, and UV-vis spectroscopies. They all decomposed above 174 o C except dye derived from 4-nitrophenol, which released nitrogen at 86 o C 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 β-naphthol produced unexpected hydroxylamine derivative in refluxing 1,4-dioxane.
