A new strategy was developed for activation of C–N bond via formation of an amine–I2 charge-transfer complex, which facilitates the inert C–N bond activation via oxidative addition with Ni(0). This strategy has been successfully applied in the Ni-catalyzed carbonylation of benzylamines via direct insertion of CO into the C–N bond, which provided a straightforward and rapid approach to arylacetamides
通过形成胺-I 2电荷转移络合物,开发了一种激活C–N键的新策略,该方法通过与Ni(0)的氧化加成促进了惰性C–N键的激活。通过将CO直接插入C–N键中,该策略已成功地应用于Ni催化的苄胺的羰基化反应,这为在催化量的I 2和Ni催化剂存在下芳基乙酰胺的制备提供了一种直接而快速的方法。机理研究表明,通过氧化加成产生的苄基自由基参与了本反应。
