A study of the photochemical reactions of some βγ-unsaturated and γδ-unsaturated 1,2-diketones is reported; it is concluded that the only efficient primary intramolecular processes involve the carbonyl group furthest removed from the alkyl chain, which may undergo cycloaddition via a five-membered transition state to give 5-oxabicyclo-[2,1,1]hexan-2-one derivatives, or γ-hydrogen abstraction leading
