We report an investigation of the Chan-Lam amination reaction. A combination of spectroscopy, computational modeling, and crystallography has identified the structures of key intermediates and allowed a complete mechanistic description to be presented, including off-cycle inhibitory processes, the source of amine and organoboron reactivity issues, and the origin of competing oxidation/protodeboronation side reactions. Identification of key mechanistic events has allowed the development of a simple solution to these issues: manipulating Cu(I) → Cu(II) oxidation and exploiting three synergistic roles of boric acid has allowed the development of a general catalytic Chan-Lam amination, overcoming long-standing and unsolved amine and organoboron limitations of this valuable transformation.

Chan-Lam 胺化的光谱研究：一种受机制启发的硼酸酯反应性解决方案

我们报告了对 Chan-Lam 胺化反应的调查。光谱学、计算模型和晶体学的结合已经确定了关键中间体的结构，并允许呈现完整的机制描述，包括非循环抑制过程、胺和有机硼反应性问题的来源，以及竞争氧化的起源/原脱硼副反应。关键机制事件的识别使得开发出解决这些问题的简单方法：操纵 Cu(I) → Cu(II) 氧化和利用硼酸的三种协同作用，开发了通用催化 Chan-Lam 胺化，克服了这种有价值的转化长期存在且未解决的胺和有机硼限制。
