Abstract
Hydrogenation of ruthenium chloride in acetonitrile yields complexes of the type Ru(CH3CN)(n)Cl6-n of which three are isolated (n = 2, 3, 4). Their fo rmation is traced by voltammetry. Ru(CH3CN)(2)Cl-4 and Ru(CH3CN)(3)Cl-3 hav e been characterized by single-crystal X-ray diffraction. Voltammetry shows that Ru(CH3CN)(3)Cl-3 acts as a mediator for oxidation of cyclohexene, met hylcyclohexene, 1-tetralol and tetralin. Its role in tetralin oxidation is illustrated by preparative scale electrolysis. The compounds Ru(CH3CN)(2)Cl -4 and Ru(CH3CN)(4)Cl-2 did not react with any of the mentioned hydrocarbon s.
