ABSTRACT
The results obtained from these efforts, conducted over a 30-year period, show that, in general, direct irradiation of
β
,
γ
-unsaturated ketones yields products resulting from 1,3-acyl migration, while triplet-sensitized reactions of these compounds affords cyclopropyl ketones by oxa-di-
π
-methane (ODPM) rearrangement pathways.
