在此，我们报道了一种镍催化的烯烃加氢化反应，得到了带有B(2)针(2)和化学计量的水的反Markovnikov型烷基硼烷。使用空气和湿度敏感的硅基硼烷进行的硅氢化反应也在优化的条件下进行。反式二苯乙烯和D2O的反应导致了1，2-H的迁移，表明反应通过β-氢化物消除和再插入机理进行。(C)2018爱思唯尔有限公司。保留所有权利。
Herein we report a Ni-catalyzed formal hydroboration of olefins, which afforded anti-Markovnikov-type alkylboranes with B(2)pin(2) and a stoichiometric amount of water. Formal hydrosilylation using air- and moisture-sensitive silylboranes also proceeded under optimized conditions. The reaction with trans-stilbene and D2O resulted in 1,2-H migration, which suggested that the reaction proceeded via beta-hydride elimination and reinsertion mechanisms. (C) 2018 Elsevier Ltd.
