• Nickel-Catalyzed Electrochemical Couplings of Vinyl Halides:  Synthetic and Stereochemical Aspects
  作者：C. Cannes、S. Condon、M. Durandetti、J. Périchon、J.-Y. Nédélec

  DOI：10.1021/jo000182f

  日期：2000.7.1

  Homo- and cross-coupling involving alkenyl halides have been performed efficiently using an electroassisted nickel-complex catalysis. Valuable product such as conjugated dienes, beta,gamma- or gamma,delta-unsaturated esters, ketones, or nitriles, as well as alkenylated aryl compounds are thus prepared with high yields and high stereoselectivity. Partial isomerization is only observed in a few cases, when the alkenyl halide is involved in a late step of the catalytic cycle. This is the case in the preparation of (Z,Z)-1,3-diene.
