Abstract

The kinetics and mechanisms of propadiene polymerization under the influence of [Rh(CO)2Cl]2, Rh(CO)2P(C6H5)3Cl, Rh(CO)3Cl are reported. The reaction rates are first-order in Rh(CO)2P(C6H5)3Cl and Rh(CO)3Cl and half-order in [Rh(CO)2Cl]2. They are second-order in the substrate for Rh(CO)3Cl and [Rh(CO)2Cl]2 and first-order for Rh(CO)2P(C6H5)3Cl. The data are interpreted in terms of a common intermediate mechanism. The formation of this common intermediate is the rate-determining step. A solvent effect is also discussed.
