  描述：

  在 K₂CO₃ 、 dimethyl-(1-diazo-2-oxopropyl)phosphonate 作用下， 以 甲醇 为溶剂， 以75%的产率得到(1,2-diethynyl-3,4-bis(trimethylsilyl)-η4-cyclobutadiene)(η5-cyclopentadienyl)cobalt
  参考文献：
  名称：

  An alternative synthesis of Vollhardt’s [1,2-diethynyl-3,4-bis(trimethylsilyl)cyclobutadiene]cyclopentadienylcobalt and selective formation of its dimer

  摘要：

  Coupling of bistrimethylsilylpropargylic alcohol over CpCo(CO)(2) to give the respective ortho and para bishydroxymethyl substituted cyclobutadiene complexes is reported. The trimethylsilyl groups have a stereo directing effect furnishing an 8:1 ratio of ortho/para. Transformation of the hydroxymethyl groups leads to the formation of the title compound [1,2-diethynyl-3,4-bis(trimethylsilyl)cyclobutadiene]cyclopentadienylcobalt. (C) 1999 Elsevier Science S.A.
