In this work, the reactions of iodine(iii) reagents (PhI(L)2: L≤pyridine, acetate (OAc-), triflate (OTf-)) with iridium(i) and rhodium(i) complexes (Vaskas's compound, Wilkinson's catalyst, and bis[bis(diphenylphosphino)ethane]rhodium(i) triflate) are reported. In all cases, the reactions resulted in two-electron oxidation of the metal complexes. Mixtures of products were observed in the reactions of Iiii reagents with Vaska's compound and Wilkinson's catalyst via ligand exchange and anion scrambling. In the case of reacting Iiii reagents with chelating ligand-containing bis[bis(diphenylphosphino)ethane]rhodium(i) triflate, no scrambling was observed.
