Arylazo derivatives of quinoxaline (1,4-benzodiazine), 1,4-benzothiazine, and 1,4-benzoxazine have been prepared by condensation of hydrazidoyl halides with o-phenylenediamine, o-aminophenol, and o-aminophenol, respectively (Table I).This method seems to

3-Aryl-2H-1,4-benzothiazines have been converted into cyanine dyes by condensing their hydroperchlorates with aldehydes, and into azo-compounds by coupling with reactive diazonium salts. The azo-compounds were also obtained by condensing arylglyoxal hydra
