Abstract

A series of a-diketones and benzils were examined for their effectiveness as sensitizers in the photoepoxidation reaction. The reduction potentials of these a-diketones were also determined at a hanging-mercury-drop electrode. The reduction potentials of the p, p'- disubstituted-benzils were successfully correlated to the sum of the Hammett u values. No evidence could be found that electron transfer plays an important role in the epoxidation ...
