A copper-catalyzed decarboxylative trifluoromethylation of (hetero)aromatic iodides has been developed. Importantly, this new copper-catalyzed reaction operates in the absence of any ligands and metal additives. The protocol shows good functional group tolerance and is compatible with heteroaromatic systems. The reaction proved scalable to a 15 mmol scale with increased yield. Finally, late-stage installation
已经开发了铜催化(杂)芳族碘化物的脱羧三氟甲基化。重要的是,这种新的铜催化反应在没有任何配体和金属添加剂的情况下进行。该协议显示出良好的官能团耐受性,并且与杂芳族系统兼容。事实证明该反应可扩展至15 mmol规模,且产率提高。最后,三氟甲基官能团的后期安装提供了抗抑郁药Prozac的N-三氟乙酰胺变体,证明了所开发方法的适用性。
