Introduction of a substituent into ortho-position of β-aryl group in a vinyl bromide resulted in the preferential formation of a vinyl cation in the photolysis.It is considered that the steric repulsion of β-aryl groups makes a convenient conformation for an electron transfer from the aromatic ring to the halogen atom in the radical pair.

Photolysis of β,β-bis(o-methoxyphenyl)-substituted vinyl bromides gave benzofuran derivatives which are derived from an intramolecular nucleophilic attack of the methoxyl group on an intermediate vinyl cation.With α-aryl-substituted vinyl bromides, only o
