Catalytic reduction of carbon dioxide by a zinc hydride compound, [Tptm]ZnH, and conversion to the methanol level†
Abstract
The zinc hydride compound, [Tptm]ZnH, may achieve the reduction of CO2 by (RO)3SiH (R = Me, Et) to the methanol oxidation level, (MeO)xSi(OR)4−x, via the formate species, HCO2Si(OR)3. However, because insertion of CO2 into the Zn–H bond is more facile than insertion of HCO2Si(OR)3, conversion of HCO2Si(OR)3 to the methanol level only occurs to a significant extent in the absence of CO2.
