  摘要：

  2-Chloro-and 2-bromo-1,1-diferrocenylcyclopropanes were synthesized as Z- and E-isomers with respect to the ferrocenyl substituent having a bisector orientation. The structure of Z-2-chloro- 1, 1 -diferrocenylcyclopropane was confirmed by X-ray diffraction analysis. Treatment of the resulting monohalides with potassium tert-butoxide in dimethyl sulfoxide afforded 3,3-diferrocenylcyclopropene in 20%' yield. The small ring in halogen- substituted diferrocenylcyclopropanes and diferrocenylcyclopropene is readily cleaved to give predominantly 3-ferrocenyl-1H-cyclopentaferrocene.

  Dehydrohalogenation of isomeric 2-chloro- and 2-bromo-1,1-diferrocenyleyclopropanes (Z- and E-isomers with respect to the 'bisecting' ferrocenyl substituent) under the action of Bu'OK in DMSO afforded 3,3-diferrocenylcyclopropene. In solution, this underwent facile opening of the small ring to give 3-ferrocenyl-1H-cyclopentaferrocene ( similar to 55%) and 1,1-diferrocenylpropene (15%). The spatial structure of Z-2-chloro-1,1-diferrocenylcyclopropane and 1,1-diferrocenylcyclopropane were elucidated by X-ray diffraction analysis of a single crystal. (C) 2002 Elsevier Science B.V.
