Diazotization reaction of 3, 7-diaminodibenzothiophene 5, 5-dioxide was examined and 3, 7-diiodo- and 3, 7-dithiocyanato-dibenzothiophene 5, 5-dioxide were prapared. Several bis-azo dyes were synthesized by diazotization of 3, 7-diaminodibenzothiophene 5, 5-dioxide followed by coupling with 21 kinds of compounds of the phenol, amine, and sulfonic acid series as the β-component.
