amination of arene through C–H bond cleavage employing N-fluorobenzenesulfonimide (NFSI) as the amination reagent in good to excellent yields with broad arene scope in the absence of any metal, ligand or additive is reported. Unlike previous transition metal-catalysed aminations in which high reaction temperatures are usually necessary, this novel reaction at room temperature is the first example of C–H
据报道,在不使用任何金属,配体或添加剂的情况下,使用N-氟苯磺酰亚胺(NFSI)作为胺化试剂,通过TEMP键催化的芳烃通过C–H键断裂的直接胺化反应具有良好的收率和优异的收率。与以前通常需要高反应温度的过渡金属催化胺化反应不同,这种在室温下的新颖反应是通过有机催化实现的NFSI的C–H胺化反应的第一个例子。还提出了这种简洁胺化的可能机理。
