The photochemical reaction of [Ru-3(CO)(12)] with thioether ligands in THF leads to the isolation of tetranuclear ruthenium-carbonyl cluster compounds of the formula [Ru-4(CO)(13)(mu(2)-R2S)]. In these compounds, ruthenium atoms adopt a typical butterfly arrangement. If chelating ligands with two thioether functions are introduced, the reaction leads to mixtures of the trinuclear substitution products [Ru-3(CO)(10)(RS boolean AND SR)] and [Ru-3(CO)(8)(RS boolean AND SR)(2)]. The latter may be...The photochemical reaction of [Ru-3(CO)(12)] with thioether ligands in THF leads to the isolation of tetranuclear ruthenium-carbonyl cluster compounds of the formula [Ru-4(CO)(13)(mu(2)-R2S)]. In these compounds, ruthenium atoms adopt a typical butterfly arrangement. If chelating ligands with two thioether functions are introduced, the reaction leads to mixtures of the trinuclear substitution products [Ru-3(CO)(10)(RS boolean AND SR)] and [Ru-3(CO)(8)(RS boolean AND SR)(2)]. The latter may be oxidatively cleaved by the use of chlorinated solvents to produce the mononuclear compound [Ru(CO)(2)Cl-2(RS boolean AND SR)] or the dinuclear complex [Ru-2(CO)(2)(mu(2)-Cl)(2)Cl-2(RS boolean AND SR)(2)] depending on the reaction conditions. Five new ruthenium-carbonyl-thioether complexes were characterized by X-ray diffraction. » weiterlesen» einklappen
