Photosensitized (electron transfer)[2e + 4e] dimerization and cross-cycloaddition of phenylated olefins: trapping the intermediate
Abstract
If the photosensitized (electron transfer) dimerization of 1,1-diphenylethylene or cross-cycloaddition of 1,1-diphenylethylene with methylpropene is carried out in the presence of acrylonitrile or methyl acrylate, alkylated tetrahydronaphthalenes are obtained, consistent with trapping of the intermediate triene via an ‘ene’ reaction.
