An efficient reduction of aromatic and aliphatic esters with 1,1,3,3-tetramethyldisiloxane in combination with [MoO2(acac)2] or [V(O)(OiPr)3] is reported. In the former system, the presence of triphenylphosphane oxide allows high conversion and good isolated yield to be reached. For the latter system, no ligand is necessary to obtain the corresponding alcohols with similar results.
据报道,使用 1,1,3,3-四甲基二硅氧烷与 [MoO2 (acac) 2] 或 [V (O) (OiPr) 3] 组合可有效还原芳香族和脂肪族酯。在前一种系统中,三苯基氧化膦的存在允许达到高转化率和良好的分离产率。对于后一种系统,无需配体即可获得具有相似结果的相应醇。
