A nickel‐catalyzed cross‐coupling between (hetero)arylborons and unactivated 1‐bromo‐1,1‐difluoroalkanes has been developed. The use of two ligands (a bidentate bipyridine‐based ligand, 4,4′‐ditBu‐bpy, and a monodentate pyridine‐based ligand, DMAP) offers a highly efficient nickel‐based catalytic system to prepare difluoroalkylated arenes which have important applications in medicinal chemistry.
已经开发出了(杂)芳基硼与未活化的1-溴-1,1-二氟烷烃之间镍催化的交叉偶联反应。使用两种配体(基于双联吡啶的配体4,4'-ditBu-bpy和基于单齿吡啶的配体DMAP)提供了高效的镍基催化体系,用于制备在二氟烷基化芳烃中具有重要应用药物化学。
