3-Aryl-1,2-cyclohexanediones 4 are prepared conveniently by photolysis of the corresponding 2-((arylsulfonyl)oxy)cyclohex-2-enones 1.The reaction was shown to occur from a triplet excited state.A biphotonic process involving the normal photo-Fries product 14 as an intermediate was ruled out by preparing and irradiating this compound.The difference of reactivity between 1 and 2-((arylsulfonyl)amido)cyclohexenones is discussed.
