Description Oxidative addition of diaryldichalcogen ligands (REER) to ruthenium carbonyl (Ru-3(CO)(12)) followed by the addition of halogen (X-2) afforded chalcogen-bridged Ru(II)-based metallacycles of general formula [X(CO)(3)Ru(mu-ER)(2)Ru-(CO)(3)X] (1-10), where E = S, Se, and Te; R = phenyl, tolyl, and benzyl; and X = Br and I. Compounds 1-10 were characterized using IR, UV-vis, and NMR spectroscopic techniques. Molecular structures of the metallacycles have been elucidated by single-crystal X-ray diffraction methods that confirm the dimeric nature of metallacycles, wherein the two Ru(CO)(3)X moieties are held together by the bridging aryl chalcogenide ligands.
