Facile Aerobic Alkylation of Rhodium Porphyrins with Alkyl Halides

Alkylation of rhodium porphyrins was achieved in moderate to high yields in the presence of air and water. With this facile alkylation method, various alkyl RhIII(por) species, including those with tertiary alkyl, were synthesized. Mechanistic

Ligand-enhanced aliphatic carbon-carbon bond activation of nitroxides by rhodium(II) porphyrin

Rh(tmp) underwent Ph3P-enhanced aliphatic carbon-carbon bond activation with various nitroxides. (Ph3P)Rh(tmp), rapidly formed from Rh(tmp) and Ph3P, enhanced the rate, selectivity, and yield in comparison to Rh(tmp). From kinetic studies, the rate of reaction showed a first-order dependence on both Rh(tmp) and TEMPO (TEMPO = 2,2,6,6- tetramethylpiperidine-1-oxyl) and saturation kinetics on Ph3P. The rate enhancement of (Ph3P)Rh(tmp) over Rh(tmp) was estimated to be about 11 at 70 °C.

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.
