摘要

Abstract: Triplet lifetimes in deaerated cyclopentane have been measured for a variety of ring-substituted benzophenones, acetophenones, and aaa-trifluoroacetophenones. The ketones undergo photoreduction under these conditions to mixtures of products formed from cyclopentyl and hemipinacol radicals. That triplet lifetimes are determined by rates of hydrogen abstraction from solvent is indicated by lifetimes being three times longer in ...
