method for oxidative amination of azoles with tertiary amines via copper-catalyzed C−H and C−N bond activation has been developed. This protocol can be performed in the absence of external base and only requires atmospheric oxygen as oxidant. The catalyst system is very simple and efficient, which opens a new way for using tertiary amines as nitrogen group sources for C−N bond formation reactions.
通过铜催化的CH和CN键活化作用,开发了一种高效,概念上新颖的用叔胺氧化唑类胺的方法。该方案可以在不存在外部碱的情况下进行,并且仅需要大气中的氧气作为氧化剂。催化剂体系非常简单和高效,这为使用叔胺作为C-N键形成反应的氮源提供了新途径。
