Abstract: 4-Arylazo-5-acetamido acenaphthenes (Va-f)and 4-arylazo-5-N-(β-cyanoethylamino)acenaphthenes (VIa-f) were prepared from 4-arylazo-5-aminoacenaphthenes (IVa-f)-by acetylation and cyanoethylation respectively. The compounds IVa-f were obtained by coupling 5-aminoacenaphthene (II) with aryl diazonium salts (IIIa-f). The compounds Va-f and VIa-f when applied on polyester and polyamide fibres as disperse dyes gave golden yellow to scarlet shades with good pick-up and moderate light fastness. These compounds also exhibited very good sublimation fastness on polyester fibres.
