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.
氢化锌化合物 [Tptm]ZnH 可通过 (RO) 3 SiH (R = Me, Et)将CO 2还原至甲醇氧化水平 (MeO) x Si(OR) 4- x,通过甲酸盐,HCO 2 Si(OR) 3。然而,由于将 CO 2插入 Zn-H 键比插入 HCO 2 Si(OR) 3更容易,因此 HCO 2 Si(OR) 3向甲醇水平的转化仅在没有一氧化碳2。
