Photochemistry of Epoxyquinones. Part 7. Photo-induced Cycloaddition of 2,3-Dimethyl-2,3-dihydro-2,3-epoxy-1,4-naphthoquinone to Olefins

Irradiation of 2,3-dimethyl-2,3-dihydro-2,3-epoxy-1,4-naphthoquinone (1a) in benzene gave the carbonyl ylide (2a) or the 1,3-diradical (3a), which was trapped with a variety of olefins, including simple alkenes, cycloalkenes, aromatic olefins, allyl acoho

SELECTIVE α-CLEAVAGE IN PHOTOLYSIS OF 7-SUBSTITUTED-6,9-DIMETHYL-6,7,8,9-TETRAHYDRO-6α,9α-EPOXYBENZOCYCLOOCTENE-5,10-DIONE

Photolysis of the title compounds in benzene gave spirophtalides and E- and Z-alkylidene phtalides via preferential α-cleavage at the more crowded side.On the basis of quantum yields and triplet lifetimes, this preference is indicated to arise from the different efficiences of the radical recombination of possible biradicals.
