α-substituted acroleins with triethylsilane and water under Pd/C catalysis and aerobic conditions. The reaction is composed of a Pd/C-catalyzed conjugate reduction step and a hydroperoxidation step. The hydroperoxidation takes place via autoxidation of sufficiently stable enols formed in situ by transfer hydrogenation. Upon reduction, 2,2-disubstituted 1,2-diols are obtained directly from aldehydes.
在 Pd/C 催化和有氧条件下,可以从 α-取代的丙烯醛与三乙基硅烷和水获得醛 α-氢过氧化物。该反应由 Pd/C 催化的共轭还原步骤和氢过氧化步骤组成。氢过氧化通过转移氢化原位形成的足够稳定的烯醇的自动氧化而发生。还原后,直接从醛得到 2,2-二取代的 1,2-二醇。
