Catalytic reduction of carbon dioxide by a zinc hydride compound, [Tptm]ZnH, and conversion to the methanol level

The zinc hydride compound, [Tptm]ZnH, may achieve the reduction of CO 2 by (RO) 3 SiH (R = Me, Et) to the methanol oxidation level, (MeO) x Si(OR) 4− x , via the formate species, HCO 2 Si(OR) 3 . However, because insertion of CO 2 into the Zn-H bond is more facile than insertion of HCO 2 Si(OR) 3 ,...

Description
Summary:The zinc hydride compound, [Tptm]ZnH, may achieve the reduction of CO 2 by (RO) 3 SiH (R = Me, Et) to the methanol oxidation level, (MeO) x Si(OR) 4− x , via the formate species, HCO 2 Si(OR) 3 . However, because insertion of CO 2 into the Zn-H bond is more facile than insertion of HCO 2 Si(OR) 3 , conversion of HCO 2 Si(OR) 3 to the methanol level only occurs to a significant extent in the absence of CO 2 . The zinc hydride compound, [Tptm]ZnH, is capable of reducing CO 2 to the methanol level.
