Direct alkylation of arenols with alkyl organometallic reagents has never been approached. Herein we reported the first successful example of nickel‐catalyzed methylation of arenols with methyl Grignard reagents to construct C(sp2)‐C(sp3) bond under mild conditions. The transformation was compatible with broad substrate scope of 2‐naphthol derivatives. Benzyl alcohol and biphenols were also suitable
从未有过使用烷基有机
金属试剂将
芳烃直接烷基化的方法。在这里,我们报道了第一个成功的例子,该例子是在温和条件下用甲基
格氏试剂进行
镍催化的
芳香烃甲基化,以构建C(sp 2)-C(sp 3)键。该转化与

苄醇和联
苯酚也是该甲基化的合适底物。
