  Semimasked 1,1′-diethynylferrocenes: synthetic concepts, preparations, and reactions

  摘要：

  Due to the inherent instability of 1,1'-diethynylferrocene, the respective coupling chemistry for the access of oligonuclear systems requires stepwise preparative sequences involving consecutive ethyne deprotection, or the conversion of latent ethyne precursor functionalities, respectively. The new derivatives 1-acetyl-1'-ethynylferrocene, 3, and, preferably, 1-ethynyl-1'-formylferrocene, 9, turned out to be the most favorable starting compounds. The subsequent synthetic chemistry, as well as the X-ray structures of selected starting and target derivatives are presented. A unique intramolecular coupling product, 12, represents the first ladder-type tricyclic metallocenophane system exhibiting high ring strain. Supplementary novelties concerning monoacetylenic parent systems are also presented. (C) 2001 Elsevier Science B.V. All rights reserved.
