Abstract

Gas-phase reactivity of the copper hydride anions [CuH2]– and [Cu2H3]– toward a range of neutral reagents has been examined via multistage mass spectrometry experiments in a linear ion trap mass spectrometer in conjunction with isotope labeling studies and Density Functional Theory (DFT) calculations. [CuH2]– is more reactive than [Cu2H3]–, consistent with DFT calculations, which show it has a higher energy HOMO. Experimentally, [CuH2]– was found to react with CS2 via hydride transfer to give thioformate (HCS2–) in competition with the formation of the organometallic [CuCS2]– ion via liberation of hydrogen; CO2 via insertion to produce [HCuO2CH]–; methyl iodide and allyl iodide to give I– an..
