利用Cu(OAc)2- [Cp * RhCl 2 ] 2双金属催化体系,开发了一种由芳基酮O-乙酰基肟和内部炔烃合成氮杂杂环的方法。该反应在具有广泛取代基的肟的反-和顺-异构体上进行。Cu-Rh双金属系统可用于合成异喹啉以及β-咔啉,呋喃[2.3- c ]吡啶,吡咯并[2,3- c ]吡啶和噻吩并[2,3- c ]吡啶衍生物。
Copper-Catalyzed Unstrained C–C Single Bond Cleavage of Acyclic Oxime Acetates Using Air: An Internal Oxidant-Triggered Strategy toward Nitriles and Ketones
A copper-catalyzed aerobic oxidative C–C single bondcleavage of acyclic unstrained oxime acetates is reported, providing various aryl nitriles and ketones in good yields. Mechanistic studies indicate a radical procedure is involved in this transformation, and the oxygen atom in the ketone products is originated from O2 in the air. Oxime acetates as an internal oxidant have been proved to be an initiator
