focus on aryl fluorides. This innovative methodology has been successfully expanded to encompass a diverse array of aryl halides, underscoring its versatility and broad applicability. The nickel-catalyzed protocol utilizes acetonitrile under mild temperature conditions, providing a clean and safe alternative for cyanation. Notably, it employs a nonhazardous, nongaseous, metal-free cyanide source and demonstrates
我们提出了一种高效的方法来氰化具有挑战性的基材,特别关注芳基氟化物。这种创新方法已成功扩展到涵盖多种芳基卤化物,强调了其多功能性和广泛的适用性。镍催化方案在温和的温度条件下利用乙腈,为氰化提供了清洁、安全的替代方案。值得注意的是,它采用无害、非气态、不含金属的氰化物源,并具有广泛的底物范围,可容纳芳基氯、氟化物、溴化物和碘化物。该反应对于乙腈特别有效。这种催化氰化过程是合成来曲唑、西酞普兰和其他 NNRTI 药物等药物的宝贵途径。从机理上讲,我们认为涉及零价镍和二价镍的催化循环对于该反应更为合理。
