摘要：

The functionalized complexes 3a-d [(dppe)Cp*Fe(C=C-L)] (L = 4-Py, 3-Py, 2-Py) were isolated with good yields from the alkynyl complex 1 [(dppe)Cp*Fe(C=CH)1 (dppe = 1,2-bis(diphenylphosphino)ethane) from the corresponding bromopyridines using a Sonogashira-coupling reaction. These redox active compounds are stable under two redox states and react as usual pyridyl ligands towards methyl iodide or (THF)W(CO)(5). They allow easy access to the corresponding pyridinium salt 4a or to the dimetallic iron-tungsten complex 5a. (C) 1999 Elsevier Science S.A. All rights reserved.
