Unexpected formation of 4-aryl-3-cyano-6-phenylpyridine-2(1H)-thiones from the reaction of arylmethylenecyanothioacetamides with benzoyl-1,1,1- trifluoroacetone

4-Aryl-3-cyano-6-phenylpyridine-2(1H)-thiones, used in the synthesis of substituted 2-alkylthiopyridines, thieno[2,3-b]pyridines, and 1,4-di(pyridin-2-ylthio)butane, have been synthesized by the condensation of arylmethylenecyanothioacetamides with benzoyl-1,1,1-trifluoroacetone. The reaction path includes the formation of the Michael adduct which undergoes loss of the acyl group. The structure of 3-cyano-2-methylthio-4-(1-naphthyl)-6- phenylpyridine has been studied by X-ray crystallography. 2005 Springer Science+Business Media, Inc.
