1,1′-Bis(2-pyridylthio)ferrocene: a new ligand in gold and silver chemistry

Abstract

The treatment of FcLi 2 ؒTMDA with pyS-Spy (py = 2-pyridyl) leads to the new ferrocene derivative Fc(Spy) 2 1. The reaction of 1 with gold() or gold() complexes gives heterometallic complexes of the type [ {Au(C 6 F 5 )} 2 {Fc(Spywhere the coordination of the gold centres takes place through the nitrogen atoms as evidenced by two crystal structure determinations. Complex 1 also reacts with silver complexes to afford derivatives such as [Ag(OTf ){Fc(SpySubstitution of the triflate ligand in [Ag(OTf ){Fc(Spy) 2 }] by bidentate ligands such as phen or SdppmS gives [Ag(phen){Fc(Spy) 2 }]OTf or [Ag(SdppmS){Fc(Spy) 2 }]OTf. The silver complex [Ag 2 {Fc(Spy) 2 } 3 ](OTf ) 2 has also been characterised by X-ray diffraction showing three 1,1Ј-bis(2-pyridylthio)ferrocene ligands bridging two silver atoms.DALTON

“…[9,37] The reason for this is that the conjugated π-electron systems between the two metals allow communication, [38] and the electron-withdrawing nature of the coordinated metal centers makes the ferrocene unit harder to oxidize. [39] …”

“…[19] Other ligands also show shifts in the ν(CϪS) peaks to lower energies in their complexes. A characteristic peak due to the rocking mode of the methyl group, δ(CϪCH 3 ) is assigned in the region 800Ϫ850 cm…”
