Abstract

The synthesis and characterisation of a small series of tethered ruthenium(II) η6-arene complexes is described, where a single benzylic substituent is examined as a route to enforcing chirality at the metal centre upon ligation of a tethered bidentate ligand. The application of these complexes as catalysts in the asymmetric transfer hydrogenation of ketones is described, with moderate enantioselectivities confirming the validity of the approach.
