Synthesis, characterization and DFT studies of 1, 1a€2-Bis(diphenylphosphino)ferrocene substituted diiron complexes: Bioinspired [FeFe] hydrogenase model complexes

摘要

The reaction of [Fe2(CO)6(e???-toluene-3, 4-benzenedithiolate)] 1 and bidentate diphosphine, 1, 1a€2-bis(diphenylphosphino)ferrocene (dppf) has been studied. New complexes obtained have been characterized by various spectroscopic techniques as bioinspired models of the iron hydrogenase active site. The crystal structure of [Fe2(CO)5(e??…1-dppfO)(e???-toluene-3, 4-benzenedithiolate)] 4 is reported.
