## Abstract n‐π^\*^ Excitation of 6‐fluoro‐4,4‐dimethyl‐2‐cyclohexenone in the presence of 2,3‐dimethyl‐2‐butene leads selectively to the formation of the corresponding oxetane. The factors which influence the oxetane __vs.__ cyclobutane formation ratio in photoadditions of cyclic enones to olefins
