The asymmetric transfer hydrogenation of ketones using isopropyl alcohol (IPA) as hydrogen donor in the presence of novel manganese catalysts is explored. The selective and active systems are easily generated in situ from [MnBr(CO)5] and inexpensive C 2-symmeric bisoxalamide ligands. Under the optimized reaction conditions, the Mn-derived catalyst gave higher enantioselectivity compared with the related ruthenium catalyst.

Palladium-catalyzed room temperature transfer hydrogenation of azo compounds using recyclable polymer-supported formate as the hydrogen donor produces corresponding amine(s) in excellent yields (88%–98%). This method was found to be highly facile with selectivity over a number of other functional groups such as halogen, alkene, nitrile, carbonyl, amide, methoxy, and hydroxyl.Key words: azo compounds, catalytic transfer hydrogenation, polymer-supported formate, 10% Pd-C, amines.
