Under photooxidation in pyridine in the presence of FeCl3, mono- and disubstituted olefins gave α-chloro ketones, while tri- and tetrasubstituted olefins gave dichloro ketones with a C-C bond cleavage.The reaction was interpreted in terms of an electron-transfer mechanism occurring within the coordination sphere of the iron ion
