The catalytic behaviour of several Ru, Rh and Ir systems containing bis(oxazoline) ligands (1–6) has been tested in the asymmetric reduction of acetophenone (7) to give 1-phenylethanol (8) by hydrogenation (Ir systems), transfer hydrogenation (Ir and Ru systems) and hydrosilylation (Ir and Rh systems). Ligands 1 and 3 gave good activities, obtaining the best asymmetric induction with Ir–1 system in
