The insertion of germylene into the H-H bond; rate constant limits and thermochemistry. Ab initio and DFT calculations on the reactions of GeH(2) and SiH(2) with H(2)

The technique of laser flash photolysis in the gas-phase has been used to set limits on the rate constants for the bimolecular reaction of germylene (GeH2) with deuterium (D2) at both ambient and elevated temperatures (585 K). These limits show that the activation energy for the insertion of GeH2 in...

More Information
Summary:The technique of laser flash photolysis in the gas-phase has been used to set limits on the rate constants for the bimolecular reaction of germylene (GeH2) with deuterium (D2) at both ambient and elevated temperatures (585 K). These limits show that the activation energy for the insertion of GeH2 into the H--H bond is at least 19 (+/-6) kJ mol(-1).
