amidating reagent has been developed. This protocol is a simple, straightforward, and economic was to afford a variety of N-(2-(imidazo[1,2-a]pyridin-2-yl)phenyl)acetamide derivatives with excellent yields. A mechanistic study reveals that a reversible cleavage of C–H bond might be involved in the reaction.
已经开发了使用二恶唑酮作为酰胺化试剂的Rh(III)催化的2-芳基咪唑杂环的定向邻位酰胺化。该方案简单,直接且经济,目的是以优异的产率提供各种N-(2-(咪唑并[1,2 - a ]吡啶-2-基)苯基)乙酰胺衍生物。一项机理研究表明,该反应可能涉及C–H键的可逆裂解。
