  Nickel-Catalyzed Silaborative Dimerization of Alkynes

  摘要：

  Double insertion of alkynes into the Si-B bond of (dimethylphenylsilyl)pinacolborane proceeded in the presence of nickel(0) catalysts to give cis,cis-1-silyl 4-boryl-1,3-butadiene derivatives in a regio- and stereoselective manner. Involvement of (silyl)(2-boryl-1-alkyl-vinyl)nickel(II) intermediates in the silaborative dimerization reaction was suggested by the regiochemical preference as well as on the basis of reactions of the corresponding germylborane with alkynes in the presence of Ni, Pd, and Pt catalysts.
