Heteroaromatic thioketones react with maleic anhydride, norbornene, acrylonitrile, and styrene to form the Diels-Alder adducts, respectively.The thioketones also undergo cycloaddition with 2-chloroacrylonitrile followed by elimination of hydrogen chloride
CYCLOADDITION REACTIONS OF ARYL 2-FURYL THIONES AND 2-THIENYL THIONES WITH MALEIC ANHYDRIDE AND 2-NORBORNENE

The reactions of aryl 2-furyl thiones with maleic anhydride and 2-norbornene gave 1,4-cycloadducts.The reactions of aryl 2-thienyl thiones with maleic anhydride gave aromatized and oxidized 1,4-cycloadducts, while the reaction with 2-norbornene gave only normal cycloadducts.In these reactions, one of the double bond in the furan or thiophene ring and the thiocarbonyl group reacted as a hetero diene system.
