The nickel-catalyzed reductive olefin hydrocarbonation reaction is one of the powerful tools for the formation of C(sp³)–C bonds. However, the reductive coupling of alkenes with benzyl halides to afford alkyl–benzyl products has rarely been studied using the well-established Ni/SiH methods. Herein, we report a method of Ni-catalyzed regioselective hydrobenzylation of unactivated alkenes to afford anti-Markovnikov products using BH₃ as a reductant. This method exhibits good functional group tolerance, a wide scope and high regioselectivity. The mild conditions enable the coupling of terminal and internal alkenes with primary and secondary benzyl halides.

使用 BH3 作为还原剂，Ni 催化烯烃的区域选择性加氢苄基化以提供 C(sp3)–C(sp3) 键

镍催化的还原性烯烃烃化反应是形成 C(sp ³ )–C 键的有力工具之一。然而，很少使用成熟的 Ni/SiH 方法研究烯烃与苄基卤化物的还原偶联以提供烷基-苄基产物。_{在此，我们报告了一种使用 BH 3}作为还原剂，对未活化的烯烃进行 Ni 催化区域选择性氢化苄化以提供抗马尔可夫尼科夫产物的方法。该方法具有良好的官能团耐受性、广泛的适用范围和高的区域选择性。温和的条件能够使末端和内部烯烃与伯和仲苄基卤化物偶联。
