摘要

Abstract: Kinetics of photoreduction of aromatic ketones by aliphatic amines are consistent with a mechanism involving rapid charge-transfer interaction between the ketone triplet and amine, k,,, followed by hydrogen transfer and formation of radicals, kh, or by charge destruction and quenching, k,. The quenching property is demonstrated by retardation by tert- butylamine of photoreduction of benzophenone by 2-butylamine. Photoreduction by ...
