## Abstract Irradiation (Ξ» > 370 nm) of 4,4‐dimethoxy‐2,5‐cyclohexadienone (**1 a**) in benzene affords mainly the ketene acetal **4 a**, which then undergoes further rearrangement. The carbomethoxycyclopentenones **6** and **7** were isolated in modest yields (10–15Β°). It is conceivable that the l
