摘要：

Abstract— The light‐induced reactions of 4,4'‐dimethoxybenzophenone, benzophenone and 4,4'‐dichlo‐robenzophenone with norbornadiene and quadricyclene have been examined in time‐resolved and steady‐state modes with both acetonitrile and benzene as solvent. It is clearly demonstrated that in all cases formation of quadricyclene as a consequence of bimolccular reaction between ketone triplet and norbornadiene does not proceed via the intermediacy of an adduct biradical as has been recently proposed.
