Mononuclear hydrido and dinuclear chloro ruthenium(II) complexes derived from readily available amino-bis(phosphinite) and amino(bisaminophosphine) tridentate ligands were applied in the catalytic hydrogenation of ester derivatives. Notably, the cationic ruthenium dimer 2c proved to be an efficient pre-catalyst when used in combination with (KOBu)-Bu-t in THF at 120 degrees C and 50 bar H-2 with aromatic and aliphatic esters.
