Abstract: This dissertation deals with the application of monodentate phosphine ligands in asymmetric hydrogenation of C-C double bonds. The usefulness of rhodium catalysts containing phosphines based on the 4,5-Dihydro-3H-dinaphtho[2,1-c;1´,2´-e]phosphepine scaffold was demonstrated in the reduction of various prochiral substrates, since excellent enantioselectivities up to 96% ee were achieved. Furthermore, the properties of iron-based catalysts were studied in the field of transfer hydrogenation. Here high catalyst activities up to 2500 h-1 were obtained in the reduction of ketones.
