Ruthenium(III) complexes of amine-bis(phenolate) ligands as catalysts for transfer hydrogenation of ketones

Synthesis, structural characterization, electrochemistry and catalytic transfer hydrogenation of ruthenium(II) carbonyl complexes containing tridentate benzoylhydrazone ligands

“…Among the various metal complexes employed for transfer hydrogenation reaction, ruthenium-based complexes have gained immense attention and have proven to be effective homogeneous catalysts [15,16]. Varying levels of efficiency were observed for ruthenium complexes containing cyclometallated and N-heterocyclic carbene ligands [17,18], pincer ligands [19], Schiff base ligands [20,21], tripodal ligands [22,23], arene ligands [24,25] and phosphine-or amine-based ligands [26,27] as homogeneous catalysts for this transformation.…”

Transfer Hydrogenation of Ketones by Ruthenium Complexes Bearing Benzimidazol‐2‐ylidene Ligands

“…[5] Several recent examples of ruthenium complexes bearing phosphanes, [6] N-heterocyclic carbenes (NHCs), [7] diamines, [8] diaminodiphosphanes or aminodiphosphanes, [9] amine-bis(phenolate)s, [10] chiral phosphanes, [11] nitrogen-containing chiral ligands, [12] and nitrogencontaining heterocyclic ligands [13] have become the most prominent members for the reduction of ketones in high yields.…”

Ruthenium(II) complexes encompassing 2-oxo-1,2-dihydroquinoline-3-carbaldehyde thiosemicarbazone hybrid ligand: A new versatile potential catalyst for dehydrogenative amide synthesis

“…This is mainly due to their kinetic inertness (low-spin d 6 ), energy transfer properties, multi-electron transfer properties and their ability to have a broad range of oxidation states which in turn depend on the nature of the ligands bound to the metal [5][6][7][8]. The catalytic activity of the ruthenium complexes containing different multidentate ligands has also been well investigated [9][10][11]. Hence, ruthenium complexes containing thiosemicarbazone ligands with triphenylphosphine /triphenylarsine coligands have received much attention in the coordination chemistry.…”
