Manganese catalysts derived from tridentate P,N,N ligands can be activated easily using weak bases for both ketone and ester hydrogenations. Kinetic studies indicate the ketone hydrogenations are 0th order in acetophenone, positive order in hydrogen and 1st order in the catalyst. This implies that the rate determining step of the reaction was the activation of hydrogen. New ligand systems with varying
One chiral element is enough: A new rutheniumcatalystcontaining a rigid chiral diamine (BIDN) and a commercially available inexpensive achiral phosphane (DPPF) is highly efficient for the enantioselective hydrogenation of ketones (see scheme). High reactivity (S/C up to 100 000) and excellent enantioselectivities (up to 99 % ee) were obtained.

Substitution of the tetrahydropyrimidine ring in enantioselective acyl transfer catalyst homobenzotetramisole (HBTM) 6 with methyl groups exerts a dramatic influence on its performance in the kineticresolution of secondary alcohols. Syn-3-Methyl analogue of HBTM (9a) has proved to be superior to the parent compound in terms of catalytic activity, enantioselectivity, and synthetic accessibility.
