  A Convenient Method for the Synthesis of 2,5-Difunctionalized Phospholes Bearing Ester Groups

  摘要：

  Symmetrically and unsymmetrically 2,5-difunctionalized phospholes bearing ester groups were prepared in a one-pot procedure from the corresponding diynes and dichloro-(phenyl) phosphine via titanacyclopentadienes. The observed optical properties of the functionalized phospholes show that the pi-conjugative push-pull interaction between the 2- and 5-substituents plays an important role in controlling the light-emitting efficiency.

• Nickel(0)-Catalyzed Dimerization of Ethyl Cyclopropylideneacetates
  作者：Taishi Kawasaki、Shinichi Saito、Yoshinori Yamamoto

  DOI：10.1021/jo0255678

  日期：2002.7.1

  The dimerization of ethyl cyclopropylideneacetates proceeded in the presence of Ni(0) catalysts, and cyclic compounds or linear compounds were formed in selective manners. The structures of products were highly dependent on the structure of the substrate and the ligands bound to the catalyst. The mechanism of the reactions was discussed in detail.

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

  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.
