  Oxidation of Ru-bound thiolate thioether and its NS₄-ligand containing thiolate and thioether sulfur donors: synthesis, characterization, and X-ray structures

  摘要：

  A ruthenium complex [Ru(H2O){Et(2)NpyS(4)(O-3)(2)}]center dot(4) containing sulfinates, sulfenates S-donors, and water as co-ligand has been synthesized from oxidation of hydrazine complex [Ru(N2H4)(Et(2)NpyS(4))] (3) and completely characterized with X- ray structural analysis [Et(2)NpyS(4)(-2)=4-(diethylamino)-2,6- bis[(2- mercaptophenyl) thiomethyl] pyridine(2-)]. Complex 4 exhibits distorted octahedral coordination of the ruthenium center and the d[Ru-S-sulfinates] and d [Ru-S-sulfenates] are almost equivalent. The average d[S-O-sulfinate] at 148.0 pm is ca 10 pm longer than the average d [S-O-sulfenate] at 138.0 pm. The sulfinates IR(KBr) bands are located in the range 1132-1113 cm(-1) as two band sets, nu(SO)(asym) and nu(SO)(sym), whereas the sulfenates show a single absorbance at approximately 882 cm(-1). The lower frequency of the nu(SO) stretches of the sulfenates as compared to that of their sulfinate rivals indicates a weaker S-O bond in the sulfenates and is consistent with X- ray crystal structure data (vide infra). Oxidation of the dithiol ligand Et(2)NpyS(4)-H-2(1) under the same condition afforded the disulfide, in this case forming a macrocyclic ligand S, S-Et(2)NpyS(4) (2) as is evidenced by an X- ray crystal structure determination. Thus, the oxidation of 3 involves activation of either the oxygen or thiolate by the ruthenium center.
