Abstract

Neutral and cationic ruthenium­(II) complexes bearing a symmetrical 2,6-bis­(imidazo­[1,2-<i>a</i>]­pyridin-2-yl)­pyridine were synthesized and structurally characterized by NMR analysis and X-ray crystallographic determinations. These complexes have exhibited good catalytic activity in the transfer hydrogenation of ketones. In refluxing isopropyl alcohol, the conversion of the substrates reached up to 99%, and a TOF value of 356 400 h<sup>–1</sup> with 0.1 mol % catalyst was achieved
