The aliphatic C(alpha)-C(beta) bonds of a series of nitriles were activated by Rh(tmp) using Ph3P as the promoting ligand from 100 to 130 degrees C. Kinetic studies at 130 degrees C revealed the rate law, rate = k'K-1[Rh(tmp)][Ph3P](n) + k(3)K(2)(K-1[Ph3P])/(1 + K-1[Ph3P])[Rh(tmp)][(BuCN)-Bu-t] and suggested the carbon-carbon bond activation occurred at the coordinated (BuCN)-Bu-t with Rh(tmp) in a 1:1 ratio in the transition state.
