have been developed. These catalysts exhibit relatively moderate excited-state reduction potentials [E1/2(C*/C•–) = 1.75–1.94 V vs saturated calomel electrode (SCE)] and can efficiently promote radical-cation Diels–Alder reactions under irradiation with green light. Interestingly, β-halogenostyrenes (Ep/2 = 1.57–1.61 V vs SCE) are well tolerated, affording synthetically useful halocyclohexenes.
