Photosensitized (electron transfer)[2e + 4e] cross-cycloaddition of alkylated olefins to phenylated olefins
Abstract
The [2e + 4e] cross-cycloaddition products are formed when an acetonitrile solution of 1,1-diphenyl-ethylene or 2-phenylnorbornene and isobutene or 2,3-dimethylbut-2-ene is irradiated in the presence of the photosensitizers (electron transfer) methyl p-cyanobenzoate or 1,4-dicyanobenzene.
