摘要：

The oxidative dehydrogenation of the complexes [Ru(bipy)2(NC5H4CH2OH)]2+, [Ru(biPY)2(NC5H4CD2OH)]2+ and [Ru(bipy)2{NC5H4CH(CH,)OH}]2+ to the corresponding carbonyl species [bipy = 2,2'-bipyridine; NC5H4CH2OH = 2-(hydroxymethyl)pyridine; NC5H4CD2OH = 2-(dideuteriohydroxymethyl) pyridine; NC5H4CH(CH3)OH = 2-(1-hydroxyethyl)pyridine] has been studied in aqueous solution by kinetic and electrochemical techniques. The mechanistic scheme was found to involve the intermediacy of a ruthenium(IV)-alkoxide species, formed by disproportionaton of the ruthenium(III) complex produced in the initial step of the oxidation process. The rate-determining removal of the proton from the alpha-carbon atom of the chelate ring is general-base catalysed.
