undergoes selective dimerization and alkylarylation with alkylfluorides and aryl Grignardreagents to give 1,6‐octadienes with alkyl and aryl groups at the 3‐ and 8‐positions, respectively, by the consecutive formation of three carbon–carbon bonds. The formation of an anionic nickel complex plays an important role in forming C−C bonds with alkylfluorides.
