摘要

Nanosecond laser flash photolysis studies have been carried out of the kinetics of inter-and intramolecular phenolic hydrogen abstraction by alkoxyacetophenone, 5-alkoxyindanone, and 4-alkoxybenzophenone triplets in acetonitrile and benzene solution. Information on the geometric requirements for abstraction by carbonyl n, π* and π, π* triplets is derived from the results for a series of ketones which contain a para-phenolic moiety attached via a para- ...
