Rate constants for the gas-phase reactions of germylene with CH3OCH3, CH3OH, CD3OD and D2O at ambient temperature

Abstract

Gas-phase rate constants for the reactions of germylene, GeH2, with dimethylether (CH3OCH3), methanol (CH3OH), deuterated methanol (CD3OD), and deuterated water (D2O), have been determined at ambient temperature (295 K) and total pressures over the range 10–200 Torr of the bath gas SF6. The second-order rate constants are pressure dependent up to the maximum pressures investigated. The behaviour of GeH2 with these reactants is very similar to the behaviour observed for silylene, SiH2. Over the same pressure range the GeH2 reaction rate constants are smaller than those observed for SiH2.
