Darst. This dissertation deals with the application of monodentate phosphine ligands in asymmetric hydrogenation of CC double bonds. The usefulness of rhodium catalysts containing phosphines based on the 4,5Dihydro3Hdinaphtho[2,1c;1,́2́e]phosphepine scaffold was demonstrated in the reduction of various prochiral substrates, since excellent enantioselectivities up to 96% ee were achieved. Furthermore, the properties of ironbased 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. vorgelegt von Stephan Enthaler Rostock, Univ., Mathematisch-Naturwiss.
