FeSO4/CuCl2 yielded 1-(1-chlorocyclohexyl)ethanone as the major product consistent with 6-endo-trig cyclization of the intermediate 5-acetylhex-5-enyl radical. This strategy was extended to the ring enlargement of a series of 1-isopropenylcycloalkyl hydroperoxides. Regioselective 7- or 8-endo-trig cyclizationreactions could be achieved by treatment of the corresponding cyclopentyl or cyclohexyl hydroperoxides

Singletoxygen, or its synthetic equivalent, is generated by the action of resin-bound molybdate on hydrogen peroxide. Resin-bound peroxomolybdate converts reactant olefins to their ene, [4+2] and [2+2] cycloaddition or secondary products.
