Abstract

The regioselectivity of the oxidative electron-transfer cycloreversion of trans,trans-2,3-diphenyl-4-methyloxetane is photosensitiser dependent. With chloranil the reaction proceeds through the trans-β-methylstyrene radical cation; however, in the case of pyrylium salts, the trans-stilbene radical cation is formed.
