Abstract
UV photolysis of [Cp*Ir(CO)2](Cp*=η5-C5Me5) in supercritical CO2(scCO2) doped with H2 or C2H6 leads to the formation of [Cp*Ir(CO)(H)R](R = H or C2H5) identified by IR spectroscopy; [Cp*Ir(CO)(H)(C2H5)] can also be generated by UV photolysis of [Cp*Ir(CO)2] dissolved in supercritical ethane (scC2H6) and the efficiency of the reaction is increased greatly by the addition of H2 at high pressures to the solution.Keywords
