The goal of this doctoral thesis was to gain a better understanding of the reaction course in imine hydrogenation as well as to develop an efficient protocol for the iridium-catalysed asymmetric hydrogenation of aliphatic imines. In the course of these studies, cyclometalation of a chiral imine to an achiral iridium complex generated a chiral catalyst. The structure of the cyclometalated imine was demonstrated to influence the enantioselectivity of the catalyst as well as to be involved in the enantiodiscriminating step of the hydrogenation. The iridacycles were investigated in further detail ...
