several oxidants using a phase-vanishing (PV) method. The borane generated was directly reacted with alkenes, affording the desired alcohols in good yields after oxidation with H2O2 under basic conditions. The selective reduction of carboxylic acids with the evolved borane was examined. The organoboranes generated by the PV method successfully underwent Suzuki–Miyaura coupling. Using this PV system,
尽管硼烷是有用的试剂,但难以处理。在这项研究中,使用相消失(PV)方法从NaBH 4或n Bu 4 NBH 4与几种氧化剂原位生成了硼烷。生成的硼烷直接与烯烃反应,在碱性条件下用H 2 O 2氧化后,以高收率提供所需的醇。考察了用放出的硼烷对羧酸的选择性还原。通过PV方法生成的有机硼烷成功进行了Suzuki-Miyaura偶联。使用该光伏系统,可以在普通试管中轻松安全地进行硼烷反应。
