The Photochemical Reaction of Benzene with Ethylenes: Studies with Allyl Compounds, Enamines, Vinyl Sulphide, and 5,6-Dichlorobicyclohept-2-ene

Benzene undergoes regio- and stereo-selective meta photocycloaddition to methyl but-3-enoate and pent-1-en-4-ol but methyl allyl ketone and NN-dimethylallylamine yield only products of the addend: likewise irradiation of benzene with enamines or methyl vinyl sulphide at 254 nm does not yield photoadducts.The meta photocycloadducts of benzene with methyl but-3-enoate and vinyl acetate and the ketones obtained by oxidation of the adducts from pent-1-en-4-ol are all essentially photostable and do not undergo Norrish Type II eliminations.The dechlorination products of the meta photocycloaddition of 5,6-trans-dichlorobocyclohept-2-ene and benzene undergo a retro-Diels-Alder addition at high temperatures, but the C8H8 isomer formed is cyclo-octatetraene.
