  Butterfly topologies: new expanded carbon-rich organometallic scaffolds

  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.

  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.
