  描述：

  Ni(η2-ethyl cyclopropylideneacetate)(P(C6H11)3)2 以 toluene-d8 为溶剂， 生成 bis(1,5-cyclooctadiene)nickel (0) 、 Ni(C8H12)((E,E)-1,2-bis(exo-CHCOOEt)cyclohexane)

  名称：

  [3 + 3] Cyclodimerization of Methylenecyclopropanes: Stoichiometric and Catalytic Reactions of Nickel(0) with Electron-Deficient Alkylidenecyclopropanes

  摘要：

  Stoichiometric treatment of Ni(cod)(2) with ethyl cyclopropylideneacetate (ECPA) in the presence of PCy3 resulted in an unpredicted formation of a Ni(0) complex bearing an (E,E)-1,2-bis(exo-alkylidene)cyclohexane ligand, which stemmed from the [3 + 3] cyclodimerization of ECPA. The reaction could be expanded to a Ni(0)-catalyzed [3 + 3] cyclodimerization reaction of ester-substituted methylenecyclopropanes, giving the corresponding cyclohexane derivatives in excellent yields.
