Abstract: | The kinetics of the reactions of the complexes C3H5MC5H5 (M ? Ni, Pd) with tertiary phosphites P(OR)3 to give M[P(OR)3]4 have been investigated. For M ? Ni and R ? C2H5, there results a third-order rate law whereas for M ? Pd and R ? C6H5 a second-order rate law is observed. Possible mechanistic implications of the kinetic data will be discussed. |
