highly regioselective, fluoride‐catalyzed hydrosilylation of β‐hydroxy epoxides has been developed. The reaction is modular and applicable to the synthesis of a broad range of 1,4‐diols. Fluoride is crucial for two reasons: First, it promotes the formation of a silyl ether (which contains a Si‐H bond) and, second, it enables ringopening by an intramolecular SN2 reaction through activation of the silane
已经开发出一种新型的高度区域选择性,氟化物催化的β-羟基环氧化物的氢化硅烷化方法。该反应是模块化的,适用于多种1,4-二醇的合成。氟化物至关重要是因为两个原因:首先,它促进了甲硅烷基醚(含有Si-H键)的形成;其次,它通过分子内的S N 2反应通过硅烷的活化而使开环成为可能。该反应可以在空气中进行。

Direct Synthesis of 1,4-Diols from Alkenes by Iron-Catalyzed Aerobic Hydration and CH Hydroxylation
Various 1,4‐diols are easily accessible from alkenes through iron‐catalyzed aerobic hydration. The reaction system consists of a user‐friendly iron phthalocyanine complex, sodium borohydride, and molecular oxygen. Furthermore, the effect of additional ligands on the iron complex was examined for a model reaction. The second hydroxy group is installed by direct C(sp3)H oxygenation, which is based on
