Notes:
The substitution reaction of [Co(CO)4]- by P(OPh)3 was investigated in THF. Under a CO atmosphere, the reaction consists of an equilibrium, which, in order to be established, needs [Co2(CO)6(P(OPh)3)2]. The catalysis by this neutral carbonyl is formally related to a previously reported case, where either [Co2(CO)8] or [Co4(CO)12] was found to be necessary for the 13CO scrambling in [Co(CO)4]-. The kinetic analysis reported in this paper indicates, however, that the two CO labilizations differ in their mechanism-the substitution by P(OPh)3 is ascribed to a disproportionation-synproportionation of [Co2(CO)6(P(OPh)3)2].
