Nickel‐Catalyzed Cross‐Coupling of Non‐Activated or Functionalized Aryl Halides with Aryl Grignard Reagents

New nickel complexes can efficiently catalyze cross-coupling of unactivated and deactivated aryl chlorides and fluorides with aryl Grignard reagents. The reaction can tolerate functional groups in aryl chlorides with or without the aid of additives, depending on the substrates (see scheme).
