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.
