Abstract
RuX2(DMSO)(4) (X=Cl, cis; Br, trans) undergoes ligand substitution in N,N-dimethylformamide (DMF) to give RuX2(DMSO)(3)DMF, which catalyzes the oxidation of secondary alcohols by NMO to ketones. Kinetics of the reaction catalyzed by trans-RuBr2(DMSO)(4) differed from that of cis- RuCl2(DMSO)(4). A mechanism is proposed involving the formation of Ru( IV)oxo species as the active intermediate and a rate expression is der ived.
