Neue optisch aktive Phosphoniumsalze als Phasentransferkatalysatoren sowie die Verwendung der korrespondierenden Phosphane in der asymmetrischen Katalyse
Within this thesis, primary the application of optically active phosphoniumsalts in asymmetric phase transfer catalysis is described. Emphasis is placed on the Darzens-reaction of benzaldehyde and chloroacetophenone. First, achiral phosphoniumsalts were used under variation of the structure of the …

Zur Aromatenfunktionalisierung in Gegenwart ionischer Flüssigkeiten
The goal of this dissertation was to identify ionic liquids with a catalytic effect on the test reactions (aromatic Halex reaction and Friedel-Crafts-Acylation). Beside that, ionic liquids have been synthesized in pure form and characterised by NMR, cyclovoltammetrie, UV-vis-spectroscopy and …
