Synthesis, characterization and use of a new tethered Rh(III) complex in asymmetric transfer hydrogenation of ketones
•A new tethered Rh(III) complex containing the TsDPEN ligand was synthesized.•This complex proved efficient for asymmetric transfer hydrogenation of ketones.•High level of enantio- and diastereoselectivities was obtained for this reaction.
A new Rh(III) complex containing the TsDPEN ligand and an η6-arene connected through a carbon tether is reported. The asymmetric transfer hydrogenation of a series of ketones catalyzed by this complex using the formic acid/triethylamine system provided the corresponding alcohols with complete conversions and a high level of enantioselectivity.
