A gold‐catalyzed, Friedel–Crafts‐like benzylation of unactivated benzylic alcohols to form 1,1‐diarylalkanes has been developed. The operationally convenient method uses only 1.3 equivalents of electron‐rich arene, employs readily available starting materials, is highly reproducible, and is tolerant to moisture. Moderate‐to‐high product yields (34–99 %) with excellent regioselectivity were obtained
已经开发了一种金催化的未活化的苄醇的弗里德尔-克拉夫茨样苄基化反应,形成1,1-二芳基烷烃。操作简便的方法仅使用1.3当量的富电子芳烃,采用容易获得的起始原料,具有高度重现性,并且耐潮。获得了中等到高的产品收率(34–99%),具有出色的区域选择性。
