Ruthenium complexes of furan- and thiophene-thiolates: Structure of CpRu(dppe)SThi
摘要:
Complexes of ruthenium containing 2-furan-and 2-thiophene-thiolates with phosphine ligands have been prepared and characterized. The bis(triphenylphosphine) complexes CpRu(PPh3)(2)SR (R = C4H3O: Fu (1a), C4H3S: Thi (1b)) were prepared by the reaction of thiolato anions (FuS(-) or ThiS(-)) with CpRu(PPh3)(2)Cl. The one-pot reaction of CpRu(PPh3)(2)Cl, thiolato anions and L ligands gave CpRu(L) SR (L = bis(diphenylphosphino) methane: dppm (2); bis(diphenylphosphino) ethane: dppe (3)). The newly prepared complexes have been characterized by spectroscopic techniques (FT-IR, H-1 NMR and P-31 NMR) and by elemental analysis. The crystal structure of CpRu(dppe) SThi (3b) has been determined by X-ray diffraction. (C) 2007 Elsevier B. V. All rights reserved.
