complex as precatalyst. This approach opens new perspectives in this area as it enables the synthesis of unsymmetric tertiary amines from readily available substrates and ethanol as a C2 building block. A variety of imines bearing electron‐rich aryl or alkyl groups at the nitrogen atom could be efficiently reductively alkylated without the need for molecular hydrogen. The mechanism of this reaction, which
借用氢的策略已应用于以空气稳定的铁络合物为预催化剂的亚胺的乙基化反应。这种方法为该领域开辟了新的前景,因为它能够从容易获得的底物中合成不对称的叔胺,并以乙醇作为C 2的结构单元。可以在氮原子上带有多个富电子芳基或烷基的亚胺被高效还原烷基化,而无需分子氢。通过DFT计算和实验研究了该反应的机理,该机理显示出乙醇对其他醇的完全选择性。
