A nickel-catalyzed reductive cross-coupling reactions between polyfluoroarenes and alkyl electrophiles is reported to access substituted fluoroarenes through chelation-assisted C–F activation. Diverse primary and secondary alkyl (pseudo)halides can be employed to couple with polyfluoroarenes, showing excellent regioselectivity. Furthermore, the nickel-catalyzed asymmetric cross-coupling of polyfluoroarenes
据报道,多氟芳烃和烷基亲电试剂之间的镍催化还原交叉偶联反应通过螯合辅助的 C-F 活化获得取代的氟芳烃。多种伯和仲烷基(假)卤化物可用于与多氟芳烃偶联,表现出优异的区域选择性。此外,初步探索了镍催化的多氟芳烃与外消旋烷基卤化物的不对称交叉偶联。此外,还以losmapimod及其类似物的全合成为关键步骤,证明了题名转换的实用性。所开发的方法具有许多优点,包括经济的催化系统、可商购的烷基亲电试剂以及缺乏敏感的有机金属试剂。
