Abstract

New ruthenium complexes with 1, 8-naphthyridine (napy) or derivativesthereof as ligands have been prepared and characterized. Three groupsof complexes were obtained. The first consists of three dinuclear ruthenium complexes with two ligands (1, 8-naphthyridine and pyridopyrazine) co-ordinated to two ruthenium ions in a bridging fashion. The second consists of two ruthenium dinuclear complexes having one ligand (2,7-dimethoxy- or 2, 7-dichloro-1, 8-naphthyridine, abbreviated to dmnapy and dcnapy respectively) co-ordinated to two ruthenium atoms. Proton NMR spectra for both complexes in aqueous solution and in acetonitrile revealed the conversion of a symmetrical form, suggesting dinucleating behaviour of the ligand, into an asymmetrical form, suggesting mononucleating behaviour of the ligand. The third group consists of a mono-and a di-nuclear complex with the ligand 2, 7-di(phenylazo)-1, 8-naphthyridine. The catalytic activity of the novel naphthyridine complexes in oxidation reactions has been studied. The catalytic oxidation of alcohols and the epoxidation of trans-stilbene were examined and the different reaction rates and selectivities are discussed in a comparative way. The active high-valent species resulting from the [Ru-2(napy)(2)(H2O)(4)Cl(OH)](4+) complex is discussed in more detail.
