PHOTOCHEMICAL TRANSFORMATIONS OF 2,4,4,6-TETRAPHENYL-4H-THIOPYRAN-1,1-DIOXIDE AND SOME ITS para-SUBSTITUTED DERIVATIVES

1,2,4,5-Tetrasubstituted cyclopentadienes VIa - VIf or phenanthrene derivative VIII, respectively, were obtained as the main photoproducts upon irradiation of sulfones Ia - If and II in acetonitrile, methanol or benzene.Bridged isomers Va - Vd were isolated from the reaction of Ia - Id carried out in acetonitrile.Probable course of the investigated photochemical transformations of 4H-thiopyran-1,1-dioxides is discussed.
