Abstract

Abstract: The photoreaction of benzophenone with several conjugated dienes leads to oxetanes. Other reaction products are those resulting from transfer of triplet excitation energy from benzophenone to the diene, and hydrogen abstraction by triplet benzophenone. For the benzophenone-2, 3-dimethyl-l, 3-butadiene reaction, a mechanism of oxetane formation is proposed which involves attack of excited triplet benzophenone on a ground state diene ...
