Copper‐mediated cyanation of aryl C—H bond with removable bidenate auxiliary as a directing group has been developed, in which green and cheap acetonitrile is used as the “CN” source. By switching the reaction conditions, the C—H cyanated products and N‐Ar‐phthalimides can be provided in acceptable yields with high chemoselectivity, respectively. The use of quaternary ammonium salt is essential for
已经开发了以可移动的二齿酸酯助剂为导向基团的铜介导的芳基CH键的氰化,其中绿色廉价的乙腈被用作“ CN”源。通过切换反应条件,可以分别以可接受的收率和高化学选择性提供CH氰化氰化产物和N -Ar邻苯二甲酰亚胺。季铵盐的使用对于氰化反应至关重要。
