Thiazoles, 4H-1,3-thiazines, 4H-pyrido-1,3-thiazines, and 4H-1,3-benzothiazines have been synthesized from N-acyl-(1,3-dithiol-2-ylidene)arylethanethioamides derived from the reactions of 4-aryl-3-halogenoacylthio-4-aryl-3-(2-halogenonicotinoylthio

Acylation of 4-aryl-3-mercapto-3-isothiazoline-5-thiones (1) with acid chloride in pyridine or alternatively with acid anhydride leads exclusively to 3-acylthio-4-aryl-3-isothiazoline-5-thiones (2).Reactions of (1) with reactive acetylenes afford 2-aryl(
