(E)-β-phenylsulfonylenones, readily prepared by oxidation of the alcohols, react with a wide variety of dienes in the presence of activated silica gel. The basic elimination of the phenylsulfonyl group in the resulting adducts gives high yields of the corresponding enones, thus showing the usefulness of these dienophiles as reactive synthetic equivalents of α,β-acetylenic ketones.

As a model for light energy conversion, various acylnorbornadienes and their corresponding valence isomers acylquadricyclanes have been prepared.Among these (19) and (31) were found to be the best pair for the purpose because of the visible light absorption of (19), a high quantum yield for its photocycloaddition and a rapid and complete reversion of (31) to (19) with an acid catalyst.
