Nickel-Catalyzed Tandem Coupling of Enones, Alkynes, Alkynylzincs, and Chlorotrimethylsilane

Abstract

Abstract A nickel complex catalyzes a new tandem coupling of chlorotrimethylsilane (Me3SiCl), α,β-enones 1, alkynes 2, and di(alkynyl)zincs 7 (R′ = Bu, t-Bu, Me3Si, and Ph) to give the coupling products 3. This procedure was complementary to the reaction with alkynyltins.
