New dyes based on 3-aryl-benzo- and -naphtho-1,4-thiazines
MacKenzie, Neil E.,Thomson, Ronald H.,Greenhalgh, Colin W.
, p. 2923 - 2932 (2007/10/02)
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
