Alkylation of rhodium(III) porphyrins [RhIII(por)] was achieved under relatively mild conditions in up to 98% yields, where readily available ammonium and quinolinium salts were utilized as the alkylating agents. This transformation tolerates air and water, thus serving as a convenient method to prepare a variety of alkyl- and benzyl-RhIII(por) complexes. Preliminary mechanistic studies support an SN2-like reaction pathway involving a RhI(por) anion intermediate.
Aromatic and benzylic C-H bond activation in the system bis(dicarbonylrhodium(I))porphyrinate-hydrocarbon solvent

Metalation of C6H6 has been known for a long time as a aside reaction occuring in refluxing benzene solutions of Rh2(CO)4(TPP) (TTP = tetraphenylporphyrin). Rather than representing the intrinsic reactivity of this complex, such hydrocarbon activation proceed via RhII(por) and RhIII(por) derivatives resulting from oxidation can be extended to other aromatic substrates and represents an effecient synthetic route to certain organometallic RhIII(TPP) derivatives.

Bis(isocyanide)(octaethylporphyrinato)- and bis(isocyanide)(tetraphenylporphyrinato)rhodium(III) hexafluorophosphates undergo nucleophilic attack leading to the formation of cationic carbene derivatives or neutral carboxymethyl, amido, and alkyl complexes. The formation of the various products is related tq the strength of the nucleophile. The crystal and molecular structure of the title compound has been determined by X-ray diffraction methods. The crystals are triclinic, space group P1, with unit cell dimensions a = 16.427 (7) ?, b = 14.386 (7) ?, c = 13.268 (5) ?, α = 107.83 (4)°, β = 99.51 (4)°, γ = 77.31 (3)°, and Z = 2. The structure was solved by the heavy-atom technique and refined to R = 0.0773 for 3991 independent reflections. The rhodium atom is at the center of a slightly distorted octahedral environment.
