Aminophosphine ligands R2P(CH2)nNH 2 and ruthenium hydrogenation catalysts RuCl2(R 2P(CH2)nNH2)2

The aminophosphine ligands R2P(CH2) 2NH2 and R2P(CH2)3NH 2 (R = Ph, iPr, tBu) were isolated in good to excellent yields from the reaction of LiPR2 with Cl(CH 2)2N(TMS)2 and Cl(CH2) 3N(TMS)2, respectively, followed by hydrolysis. This approach allows fine tuning of the ligands' stereoelectronic properties through the variation of the substituents on the phosphine. The aminophosphine ligands were used to prepare the ruthenium complexes RuCl2(R 2P(CH2)2NH2)2 and RuCl2(R2P(CH2)3NH2) 2 by reacting a 2:1 mixture of the respective ligand and [RuCl 2(cod)]n in an appropriate solvent. The resulting complexes were found to be excellent catalysts for the hydrogenation of ketones and imines. The Royal Society of Chemistry 2009.
