Octaethylporphyrin and tetraphenylporphyrin Ir(I) and Ir(III) complexes are useful catalysts for intramolecular C-H insertion processes of stabilized diazo compounds. While the Ir(I) complex TPP[Ir(CO)is the most efficient and selective catalyst, the othe

A modified method for the synthesis of (TPP)[Ir(CO)3]2 from [Ir(CO)3Cl]2 and (TPP)H2 where TPP is the dianion of tetraphenylporphyrin was developed and gives a much higher percent yield. Electrochemical and spectroelectrochemical studies of (TPP)[Ir(CO)3]2 indicate that this binuclear Ir(I) complex undergoes two reversible reductions at the porphyrin π-ring system. Three irreversible oxidations are observed in benzonitrile containing 0.2 M tetrabutylammonium perchlorate, while in CH2Cl2, only two irreversible oxidations are recorded. The first oxidation occurs at one of the two Ir(I) centers of (TPP)[Ir(CO)3]2 and is followed by a rapid chemical reaction that leads to the generation of [(TPP)Ir]+ClO4- or a solvated form of this species in solution. An overall mechanism for the electrochemical conversion of binuclear (TPP)[Ir(CO)3]2 to monomeric [(TPP)Ir]+ClO4- and the additional reactions of this species are reported. Comparisons are also made between electrochemical properties of binuclear (TPP)[Ir(CO)3]2 and the binuclear Rh(I) analogue (TPP)[Rh(CO)2]2.
