摘要：

The dimer [Ir(CO)(2)I(mu-I)Me](2) 2 reacts with CO to give the tricarbonyl [Ir(CO)(3)I2Me] 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 inert atmosphere, 3 carbonylation.
