  摘要：

  Starting from either (tetraethynylcyclobutadiene)cyclopentadienylcobalt or [1,2-diethynyl-3,4-(2-dioxanyl)cyclobutadiene]-cyclopentadienylcobalt a sequence of copper and Pd-catalyzed couplings of the Eglinton and the Heck-Cassar-Sonogashira-Hagihara type furnishes five bow-tie shaped doubly annelated dehydroannulenes, the largest of which featuring a (formal) 7,8:13,14:25,26:31,32-tetra(4'alkyl-1',2'-benzo)tricyclo[18,16,0(2,19)]hexatricosa-3,5,9,11,15,17,21,23,27,29,33,35-dodecayne-1,7,13,19,25,31-hexaene hydrocarbon ligand with a cyclopentadienyl-cobalt stabilized cyclobutadiene complex as its central unit. Single crystal X-ray structures of two of the smaller butterflies are reported and their surprising solid-state packing is discussed herein. (C) 2003 Published by Elsevier Science B.V.

  The synthesis of fused organometallic dehydroannulenes containing cyclobutadiene(cyclopentadienyl)cobalt or ferrocene units separated by butadiyne linkers is presented. Starting from the corresponding 1,2-diethynylated sandwich complexes, either Eglinton, Hay, or Vogtle-type coupling furnishes the desired dehydroannulenes. The choice of the coupling variant is critical for the success of this reaction

  介绍了包含由丁二炔连接体分隔的环丁二烯（环戊二烯基）钴或二茂铁单元的稠合有机金属脱氢环烯的合成。从相应的 1,2-二乙炔化夹心复合物开始，Eglinton、Hay 或 Vogtle 型偶联提供所需的脱氢环烯。偶联变体的选择对于该反应的成功至关重要。发现对于二乙炔二茂铁，经典 Eglinton 系统的变体在吡啶中使用 Cu2Cl2/CuCl2 混合物成功地工作，而对于环丁二烯（环戊二烯基）钴配合物，使用乙腈中的 Cu(OAc)2 的 Vogtle 偶联得到了最多的结果。令人印象深刻的结果，导致环化材料的产率为 87%。为了获得过乙炔化有机金属脱氢环烯，开发了四乙炔化环丁二烯配合物的新合成方法。双丁二炔化 CpCo 连接的环丁二烯的快速真空热解提供所需的四乙炔化环丁二烯...

  A metamorphosis of the tetraethynyl precursor 1 through double Cu-catalyzed ring closure leads to the corresponding butterfly-shaped cyclobutadiene complexes 2 in high yield (94 %). Single-crystal X-ray diffraction shows that the large organic ligand is distinctly nonplanar with a concave topology. Cp=cyclopentadiene.
