Acyliridium porphyrins were synthesized by the reactions of aryl aldehydes with iridium(III) porphyrin chloride and methyl under solvent-free conditions with high yields. Selective aldehydic carbon hydrogen bond activation (CHA) was observed without any aromatic CHA in all the cases. Mechanistic investigation on the reactions with Ir(ttp)Cl(CO) suggested that (ttp)Ir cation was a likely intermediate of aldehydic CHA, whereas the CHA with Ir(ttp)Me underwent an oxidative addition or σ bond metathesis pathway. These reactions provided a facile synthesis of (arylacyl)iridium porphyrins.
