cross-coupling reaction of alkyl halides, 1,3-butadienes, and aryl-Grignard reagents has been developed by the use of a nickel catalyst. This reaction proceeds efficiently at 25 °C using (dppf)NiCl2 as a catalyst. Alkyl chlorides, bromides, and iodides can be used as suitable alkylating reagents. The reaction also proceeds when arylzinc halides are used instead of Grignard reagents. Competitive reactions of a
