Reactions with 1,8-Naphthosultam. Synthesis of Benzisothiazolobenzotriazole 4,4-Dioxide. A New Ring System

1,8-Naphthosultam (I) coupled with arenediazonium salts to give the 4-arylazo- VII, and the 2,4-bisarylazo-1,8-naphthosultams, VIa-c.On the other hand, coupling of the 4-substituted 1,8-naphthosultams afforded the 2-phenylazo derivatives, IIa,b.Reduction of IIa,b gave the 2-amino compounds IVa,b, which reacted with nitrous acid to give the benzisothiazolobenzotriazoles, Va,b, establishing thus a new ring system.The nitro analogue Vc was also synthesized.
