A general method for the Ni-catalyzed Buchwald–Hartwigamination of (hetero)arylchlorides using both anilines and aliphatic amines under homogeneous conditions has been developed. Key to the success of this method is the implementation of a dual-base strategy that utilizes an amine base combined with a soluble halide scavenger that allows for the use of a single air-stable, commercially available
开发了一种在均相条件下使用苯胺和脂肪胺对(杂)芳基氯进行镍催化 Buchwald-Hartwig 胺化的通用方法。该方法成功的关键是实施双碱策略,该策略利用胺碱与可溶性卤化物清除剂相结合,允许使用单一空气稳定的市售 Ni(II)-预催化剂和膦配体[( R , S )-Josiphos] 组合可在低至 1.0 mol% 的催化剂负载量下促进多种(杂)芳基氯和药学相关胺亲核试剂的胺化反应。
