Reactivity of bis(ferrocenyl)ethynylthioether towards triruthenium dodecacarbonyl

New ruthenium compounds have been prepared by rupture and formation of S–C bonds as well as coupling between alkyne groups with or without insertion of CO, in the reaction of FcCtriple bond; length of mdashCSCtriple bond; length of mdashCFc with Ru3(CO)12. All complexes have been characterized by analytical and spectroscopic data and the crystal structure of [Ru3(CO)9(μ3-η2,η4,η3-{FcCC(C2Fc)SC(Fc)CSCtriple bond; length of mdashCFc}) has been solved by X-ray diffraction.
