direct and atom economic C–H amidation of electron rich heteroarenes in the presence of phosphoric acid, a photocatalyst and visible light. Hetero-aromatic amides are obtained in good yields at very mild reaction conditions with dinitrogen as the only by-product. The reaction allows the use of aryl-, heteroaryl- or alkenyl acyl azides and has a wide scope for heteroarenes, including pyrroles, indole
在磷酸,光催化剂和可见光的存在下,苯甲酰叠氮用于富电子的杂芳烃的直接和原子经济的CHH酰胺化反应。杂芳族酰胺是在非常温和的反应条件下以高收率获得的,二氮是唯一的副产物。该反应允许使用芳基,杂芳基或烯基酰基叠氮化物,并具有广泛的杂芳烃范围,包括吡咯,吲哚,呋喃,苯并呋喃和噻吩,具有良好的区域选择性和产率。
