Photoaddition of benzophenone to allenic esters

Photochemical addition of benzophenone to ethylpenta-2, 3-dienoate (1a), ethyl hexa-2,3-dienoate (1b) and ethyl 4-methylhexa-2,3-dienoate (1c) furnish various mono- and dioxetanes. Novel oxetanes (2a,b) result in the reactions of (1a,b) through addition of benzophenone to electron deficient C2-C3 π-bond of the respective esters. A rationalization of the obtained modes of photoaddition has been offered.
