Arene-ruthenium complexes containing nitrogen and oxygen donor ligands

Scientific community has shown decent research interest in the field of organometallic complexes based on platinum group metals owing to their plausible use in synthetic and industrial chemistry. In this regard, transition metal complexes containing ¿6-arene, ¿5-Cp and Cp* have drawn special attention. In particular, arene complexes have emerged as versatile intermediate in organic synthesis as a consequence of the ease with which the arene ligand can be functionalized. The presence of a transition metal center and ancillary ligands on one face of the coordinated arene can serve as a valuable stereochemical element. The utility of ¿6-arene and ¿5-Cp and Cp* metal complexes emanates not only from the reactivity inherent to the coordinated ring but, also from the control over three facially disposed coordinated sites about a given metal center afforded by incorporation of an arene ligand. In search of new systems based on arene ruthenium chemistry which can behave as potential metallo-ligands, new ¿6-arene ruthenium and analogous ¿5-Cp complexes based on chelating N, N and N, O donor ligands and non-chelating nitrogen donor organic ligands has been synthesized and fully characterized.
