Abstract
[GRAPHICS] Cycloreversion of oxetane 1 is achieved using (thia)pyrylium salts as photo sensitizers. Radical cation intermediates involved in the electron-transfer process have been detected using laser flash photolysis. The experimental results are consistent with the reaction taking place from the triplet exci ted state of the sensitizer.
