Interaction of styrene with triphenylphosphinecobalt complexes

The interaction of the cobalt phosphine complexes Co(N2)(PPh3)3, HCo(N2)(PPh3)3 and H3Co(PPh3)3 with styrene yields mono and dinuclear complexes identified by the ESR method. A paramagnetic complex, Co(PPh3) (styrene)2, is one of the intermediates in the catalytic hydrogenation of styrene.
