CH₂ Linkage Effects on the Reactivity of Bis(aminophosphine)-Ruthenium Complexes for Selective Hydrogenation of Esters into Alcohols.

ABSTRACT: A novel ruthenium complex binding to two subtly different aminophosphine ligands, (o-PPh₂C₆H₄CH₂NH₂)(o-PPh₂C₆H₄NH₂)RuCl₂, was successfully isolated. This bis(aminophosphine)-ruthenium complex shows efficient activity in both dimethyl oxalate (DMO) and methyl benzoate (MB) hydrogenation. On the contrast, similar complexes (o-PPh₂C₆H₄NH₂)₂RuCl₂ and (o-PPh₂C₆H₄CH₂NH₂)₂RuCl₂, can only effectively catalyze the hydrogenation of DMO and MB, respectively. Our experimental studies in combination of theoretical calculations reveal that the remarkable
