Mechanistic studies have indicated that the triplet of acetylacetone is the active species in the photochemicalcycloaddition to cyclohexene (the de Mayo reaction). The reaction of acetylacetone can be extended to cycloolefins such as 1,5-cyclooctadiene or 1,5,9-cyclododecatriene, but not to conjugateddienes. Similar cycloadditions of 2-acetylcycloalkatones to cycloolefins yields δ-ketones which can
