Irradiation of β‐aminovinyl aryl thioketones ( 1a‐b ) afforded β‐aminovinyl aryl ketones ( 2a‐b ). 2 H ‐Thiopyran derivatives ( 4a‐b ) were obtained when β‐aminovinyl phenyl thioketone ( 1a ) was irradiated with methyl acrylate and acrylonitrile. 4 H ‐Thiopyran derivatives ( 6,8 ) were also obtained thermally in the reaction of β‐aminovinyl phenyl thioketone ( 1a ) and methyl propiolate and maleic anhydride.
