The reaction of Ru(3)(CO)(12) in chloroform with thioether ligands after 25 min of irradiation leads to the formation of mononuclear ruthenium(II) complexes of the general formula fac-[Ru(CO)(3)Cl(2)(S)] (S = thioether) if monodentate ligands are introduced. In the case of chelating bidentate thioethers a complex of the formula all-cis-[Ru(CO)(2)Cl(2)(S boolean AND S)] is produced.

In the case of chelating bidentate thioethers a complex of the formula all-cis-[Ru(CO)(2)Cl(2)(S boolean AND S)] is produced. If irradiation time is prolonged to 2.5 h mononuclear complexes of the composition trans-[RuCl(2)(S)(4)] or trans-[RuCl(2)(S boolean AND S)(2)] are observed. The use of tetrahydrothiophene (THT) in the latter case produces a dinuclear ruthenium(II) complex of the formula [Ru(2)(CO)(2)Cl(4)(THT)(2)(mu-THT)(2)] which is the first structurally characterized neutral ruthenium complex with a bridging thioether ligand. Regardless of the used ligand complexes trans-[RuCl(2)(S)(4)] or trans-[RuCl(2)(S boolean AND S)(2)] are formed from the reaction of RuCl(3)center dot H(2)O with the corresponding thioether in the presence of NEt(3) and formaldehyde in excellent yields. Six new ruthenium complexes are characterized by X-ray diffraction. » weiterlesen» einklappen
