Darst. This thesis presents the study and development of new catalysts based on first row transition metals for the (asymmetric) reduction of different C=O and C=N bonds. An iron cluster catalyst with a chiral tetradentate P2N2 ligand was discovered to catalyze the asymmetric transfer hydrogenation of N-diphenylphosphinylketimines. Subsequently the combination of a chiral Brønsted acid with a well-defined Shvo type iron complex creates an active catalyst which could hydrogenate a variety of N-aryl ketimines to amines using molecular hydrogen. Finally, an iron cluster catalyst was discovered to catalyze the reduction of amides with inexpensive PMHS. vorgelegt von Shaolin Zhou Die elektronische Ausgabe weicht von der gedruckten ab.
