Abstract

The reaction of Fc(Li)2 with diphenyl disulfide or diselenide gives the ferrocene derivatives Fc(XPh)2 (X = S, Se). These react with various gold or silver species to afford complexes where the ligand can act in either a bridging or a chelating mode. Thus gold(I) or gold(III) derivatives of the type [Au(PPh3){Fc(XPh)2}]OTf or [{Au(C6F5)3}2{Fc(XPh)2}] have been obtained by treatment of the ligands with the appropriate starting material. The reaction of Fc(XPh)2 with AgOTf in 1 ∶ 1 or 2 ∶ 1 molar ratio leads to [Ag(OTf){Fc(XPh)2}] or [Ag{Fc(XPh)2}2]OTf, respectively. Starting from [Ag(OTf)(PPh3)] the compounds [Au(PPh3){Fc(XPh)2}]OTf have been prepared. Finally, substitution of the triflate in [Ag(OTf){Fc(XPh)2}] by other ligands such as phenanthroline gives [Ag(phen){Fc(XPh)2}]OTf. The crystal structures of some of these complexes have been established by X-ray diffraction studies.
