Ruthenium(II)-catalyzed thioether oxidation. 3. Syntheses and structure of model complexes with the new linear tridentate ligand bis(3-(ethylsulfinyl)propyl) sulfide
In the first paper of this series the authors reported that an all-trans Ru(II) complex with the stoichiometry RuX/sub 2/(SR/sub 2/)/sub 2/(R/sub 2/SO)/sub 2/ (1) is the probable structure for the most oxygen-active species leading to catalysis in these thioether oxidation systems. In the second paper of this series the authors described their attempts to synthesis an all-trans-RuX/sub 2/(R/sub 2/S)/sub 2/(R/sub 2/SO)/sub 2/ complex from a symmetrical tridentate monosulfoxide ligand, 3-(ethylthio)-1-((3-(ethylthio)propyl)sulfinyl)propane (EESP). These attempts failed due to isomerization (possibly through a five-coordinate intermediate) to yield cis-halo complexes. In this paper the authors report the synthesis of a new symmetrical linear tridentate bis(sulfoxide) ligand containing the sulfoxide-sulfide-sulfoxide donor set. The synthesis and characterization of two isomeric Ru(II) complexes with this ligand are described. In order to structurally characterize these complexes, the crystal structure of minor product 9 of the reaction of trans-RuBr/sub 2/(S(CH/sub 2/)/sub 3/CH/sub 2/)/sub 4/ (2) with the ligand bis(3-ethylsulfinyl)propyl) sulfide (3; BEPS) was determined.
