Metalloradical activations of aliphatic carbon-carbon bonds of nitriles: Scope and mechanism

The C(sp3)-C(sp3) bonds of a series of α-alkylacetonitriles, 2-silylacetonitriles and 2-alkylbenzonitriles, have been activated by Rh(tmp) using Ph3P as the optimized promoter ligand at 130°C. Selective aliphatic-aliphatic carbon-carbon bond activation (CCA) occurred for α-alkylacetonitriles and 2-alkylbenzonitriles without aromatic-aliphatic or aromatic-cyanide bond activation. Competitive activations of C-Si and C-C bonds were observed for 2-silylacetonitriles. The yields of Rh(tmp) alkyls were affected by bond energy and steric hindrance of the nitriles. Kinetic studies for the carbon-carbon bond activation (CCA) of tBuCN at 130°C revealed the rate law: rate = k′K 1[Rh(tmp)]m[Ph3P]n + k 3K2(K1[Ph3P])/(1 + K 1[Ph3P])[Rh(tmp)][tBuCN]. The CCA is proposed to occur at the coordinated tBuCN with Rh(tmp) in a 1:1 ratio in the transition state.
