ResumoThe dimer [Ir(CO)2I(µ-I)Me]2 2 reacts with CO to give the tricarbonyl [Ir(CO)3I2Me] 3 identified by high pressure IR and NMR spectroscopy and isotopic labelling; kinetic data for the migratory CO insertion reaction of 3 support its role as a key intermediate in iridium catalysed methanol carbonylation.
