Web7 Apr 2024 · In this review, we summarized the structure‐activity relationship of those catalysts with different ligand skeletons and their applications in cross‐coupling reactions including Suzuki‐Miyaura coupling, Buchwald‐Hartwig amination and direct C−H acylation, via amide C−N bond activation. WebAn efficient method has been developed for the N-arylation of a variety of water-soluble amino alcohols (1.2 mmol) with aryl iodides (1.0 mmol) in water under CuI-catalyzed conditions. The reaction was conducted via substrate-promoted action and did not require an additional ligand or phase-transfer catalyst, and afforded the desired N-aryl amines in …
