The functionalizedcomplexes 3a–d [(dppe)Cp*Fe(CCL)] (L=4-Py, 3-Py, 2-Py) were isolated with good yields from the alkynyl complex 1 [(dppe)Cp*Fe(CCH)] (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
