Asymmetric catalysis has become a vital tool for modern synthetic chemists. Ferrocenes are widely-used building blocks of stereoselective catalysts; derivatives such as Josiphos rank amongst the most versatile and efficient ligands. In this thesis, a chiral ferrocene was used as a building block for the synthesis of a variety of monopnictogen ferrocenes. After a general introduction, the synthesis of aminoferrocenes is discussed and preparations and applications of novel substance classes, such as bis(ferrocenyl)NacNac and ferrocenyl ureas, are presented. Furthermore, the chiral ferrocenyl backbone was used for the preparation of phosphinoferrocenes and their potential in gold(I)- and ruthenium(II)- catalyzed reactions was assessed.
