The 2, 2-diphenylvinyl (I) and l-(p-tolyl)-2, 2-diphenylvinyl (11) radicals are formed by the thermal decomposition of the appropriate tert-butyl peresters in solvents such as cumene and tert-butylbenaene. The radicals are quenched by hydrogen donors to give the corresponding olefins in varying yields, according to the nature of the hydrogen donor, temperature, and perester concentration, Rearranged products, cis-and trans-stilbene and ...
