AlkenesQ 0083 Nickel-Catalyzed Cross-Coupling Reaction of Allyl- and Benzylzinc with Alkenyl

Sulfides. — To achieve good yields of target compounds (III), butyllithium must be added to form the Ni(0) catalyst. Coupling with zinc reagent (IV) results in formation of a mixture of regioisomers. For arylmethylzinc bromides, NiCl2(dppe) is the most effective catalyst. — (BABA, Y.; TOSHIMITSU, A.; MATSUBARA*, S.; Synlett 2008, 13, 2061-2063; Dep. Mater. Chem., Grad. Sch.
