Abstract: Tetraphenylantimony(V) carboxylates, triphenylantimony, triphenylbismuth have been used in the Pd-catalyzed C-phenylation reaction of methyl acrylate in the presence of peroxides such as (PhCO2)2, t-BuOOH, H2O2 under mild conditions (20-50 °?). The peroxides promote a cascade participation of organoantimony compound to provide transfer of two or three phenyl groups with the formation of methylcinnamate as a sole product. Organobismuth compound gives methylcinnamate, biphenyl and benzene simultaneously.
