catalytic Ni species in the presence of an environmentally benign Zn reductant, delivering allylated alkanes (see scheme). This unprecedented approach allowed a variety of unactivated alkyl halides and substituted allylic carbonates to regioselectively afford E‐alkenes in good to excellent yields.
两个亲电试剂的博弈:在环境无害的Zn还原剂存在下,使用催化性Ni物种可以连接两个部分带正电的sp 3碳原子,从而提供烯丙基化的烷烃(请参见方案)。这种前所未有的方法使各种未活化的烷基卤化物和取代的烯丙基碳酸酯能够选择性地以良好至极佳的收率选择性提供E-烯烃。
