چکیده
cis-[RuCI2(depehl (1) (depe = Et2PC2H4PEt2) is obtained in excellent yield and high isomeric purity by the reaction of [RuCliDMSO)41 with two equivalents of depe in acetone 01" ethyl acetate under reflux conditions. One of the chloride ligands is labile and readily displaced by CH3CN to afford the cationic monosubstitution product cis-[RuCl(CH3CN)(depe)21 +(2), which was isolated as the PF 6 salt. The X-ray cl"ystal structure of 1 was determined. The redox properties of 1 and 2 as weil as the chloride displacement from 1 by CH3CN were studied by cyclic and square wave voltammetry KeYlVords: Ruthenium; Nitrile complexes; Electrochemistry; X-ray analysis

Reactions of [Pd(styrene)(PR3)2], generated from trans-[PdEt2(PR3)2] and styrene, with 2 equiv. of benzyl isocyanate in THF at room-temperature afforded unusual cyclic Pd-tetramers of five-membered rings consisting of organic isocyanate dimers and palladium, [Pd(PR3){-C(O)N(R)C(O)N(R)-}]4 (PR3 = PMe3, ; PR3 = PMe2Ph, ). Additionally, a cyclic trimer, (RNCO)3, (R = benzyl) was produced as a cata...
متن کاملSyntheses of Ru-S clusters with kinetically labile ligands via the photolysis of [(cymene)3RuS2](PF6)2.
Three ruthenium sulfide clusters with labile CH3CN ligands have been photochemically synthesized. Irradiation of [(cymene)3Ru3S2](PF6)2 ([1](PF6)2) in CH3CN gives [(cymene)2(CH3CN)3Ru3S2](PF6)2 ([2](PF6)2), which has been characterized by 1H NMR spectroscopy, ESI mass spectrometry, and chemical reactivity. Treatment of [2](PF6)2 with PPh3 gives [(cymene)2(CH3CN)2(PPh3)Ru3S2](PF6)2 ([3](PF6)2) a...

The purpose of this study was to prepare high oxidation-state rhenium oxomethyl complexes, including cationic compounds, and test selected examples for olefin polymerization activity. Reaction of ReOMe2(PMe3)2Cl with pyridine N-oxide and 2,2 -bipyridine (bipy) gave cis-ReOMe2(bipy)Cl. Conversely, treatment of ReO(bipy)Cl3 with AlMe3 gave trans-ReOMe2(bipy)Cl. The compound cis-ReOMe2(bipy)Cl iso...

Inhalation of ultrafine particulate matter (PM) in air pollution increases cardiovascular mortality by passing into systemic circulation and possibly affecting endothelial cell (EC) function. This study identified the chemical constituents, including polycyclic aromatic hydrocarbons (PAHs), in diesel exhaust particulate extracts (DEPEs) prepared from a truck run at different speeds and engine l...

The cyclometallated Ru(II) complexes cis-[Ru(phpy)(phen)(CH3CN)2](PF6) (1; phpy(-)=deprotonated 2-phenylpyridine, phen=1,10-phenanthroline) and cis-[Ru(phpy)(bpy)(CH3CN)2](PF6) (2; bpy=2,2'-bipyridine) were investigated as potential agents for photodynamic therapy. The presence of phpy(-) in the coordination sphere results in a red-shift of the Ru→phen and Ru→bpy metal-to-ligand charge transfer...
