Chan-Lam Coupling_Chan-Lam耦合

这个反应允许芳基碳杂原子键的形成,通过氧化耦合的硼酸,锡或硅氧烷与空气中的N-H或O-H含化合物。底物包括酚类、胺类、苯胺类、酰胺类、酰亚胺类、脲类、氨基甲酸酯类和磺胺类。反应是由化学计量量的铜(II)或催化量的铜催化剂诱导的,该催化剂被大气氧或另一种初级氧化剂重新氧化。


Chan-lam耦合可以在室温下在空气中进行,这使得它比Buchwald-Hartwig交叉耦合具有一定的优势。


Chan-lam耦合机理

与化学计量量的铜(II)的反应也受到氧气的促进,因为从铜(III)中还原性消除更快。

A Cu-catalyzed nondecarboxylative methylation of carboxylic acids with methylboronic acid proceeds in air as sole oxidant and offers a strategy for replacing toxic, electrophilic alkylating reagents. An isotope-labeling study supports an oxidative cross-coupling mechanism, in analogy to that proposed for Chan-Lam arylation.
