Thermal decomposition of <I>trans</I>-α-phenylcinnamoyl peroxide and <I>t</I>-butyl <I>trans</I>- and <I>cis</I>-α-phenylperoxycinnamates and photolyses of 1,1 -diphenyl-2-iodoethylene and 1,1,2-triphenyl-2-iodoethylene were carried out in benzene under oxygen and their products were determined. The intermediate vinylic radicals, on reaction with oxygen, undergo oxidative cleavage and dioxygenation of their unsaturated bonds. As an example, 1,2-diphenylvinyl radicals give benzaldehyde together with benzoin.
