多氟芳烃是医学和材料化学中一类重要的化合物, 但制备烷基化多氟芳烃仍然具有挑战性. 在此, 报道了在温和条件下镍催化的多氟芳烃与烷基卤化物的还原烷基化反应. 多氟芳烃(含3~6个F的结构)可与多种类型烷基卤化物(如伯、仲、叔烷基碘化物)顺利反应. 通过Ni催化和(Bpin)2/K2CO3作为终端还原剂的结合, 实现了C(sp2)—C(sp3)键的高效生成.

关键词: 镍催化, 多氟芳烃, 烷基卤代物, 还原偶联

Polyfluoroarenes represent an essential group of compounds in the fields of medical and material chemistry. It is still a challenge to synthesize alkylated polyfluoroarenes. Herein, a Ni-catalyzed reductive alkylation of polyfluoroarenes with alkyl halides under mild conditions is reported. Polyfluoroarenes (3~6 F) can reacted smoothly with a diverse range of alkyl halides, such as primary, secondary, and tertiary alkyl iodides. The efficient formation of C(sp2)—C(sp3) can be achieved through the combination of Ni catalysis and (Bpin)2/K2CO3 as terminal reductant.

Key words: nickel catalysis, polyfluoroarenes, alkyl halides, reductive cross-coupling
