Abstract: The rate of substitution of L by a chloride ion or acetonitrile in cis-[Ru(bpy)2 (L)(X)]+ (X = NO3; L = pyridine, acetonitrile ; bpy = 2,2'-bipyridine) in low polarity solvents, is greatly enhanced over the rates observed for complexes with X = Cl, NO2, CF3CO2 and p-CH3C6H4SO3. For X = NO3, rate constants and a mechanism for formation of the final product, cis-Ru(bpy)2Cl2 or cis-Ru(bpy)2(CH3CN)2]2+, are presented. The rate enhancement for the nitrato complex is attributed to its ability to act as a bidentate ligand.
