摘要：

Photolysis of 3-phenylpropiophenones 1 a-d in the presence of 2,4,6-triphenylpyrylium tetrafluoroborate (TPT) yields the corresponding α,β-unsaturated ketones 2 a-c and 1 d (from 1 c), together with acetophenone (3), benzophenone (4), benzoic acid (5) and benzaldehyde (6), presumably by fragmentations of the radical cation 1+ ·, generated via a single electron transfer process from 1 to the excited TPT. © 1990 Springer-Verlag.
