development of the Ir(III)-catalyzed direct C-H amidation of arenes and alkenes using acyl azides as the nitrogen source. This procedure utilizes an in situ generated cationic half-sandwich iridium complex as a catalyst. The reaction takes place under very mild conditions, and a broad range of sp(2) C-H bonds of chelate group-containing arenes and olefins are smoothly amidated with acyl azides without the intervention
本文报道了使用酰基叠氮化物作为氮源的 Ir(III) 催化的芳烃和烯烃的直接 CH 酰胺化的发展。该程序利用原位生成的阳离子半夹心铱络合物作为催化剂。该反应在非常温和的条件下进行,含螯合基团的芳烃和烯烃的范围广泛的 sp(2) CH 键与酰基叠氮化物顺利酰胺化,而无需 Curtius 重排的干预。值得注意的是,芳基-、脂肪-和烯基酰基叠氮化物的各种反应物均以高官能团耐受性有效地酰胺化。使用开发的方法,Z-烯酰胺很容易获得,完全控制区域和立体选择性。
