Abstract:

The thesis is dealing with the synthesis and characterization of new type of sulfonated N-heterocyclic carbene ligands in their stable form. These ligands are successfully utilizied as in situ catalyst for the cross coupling reactions, namely Suzuki-Miyaura Coupling reaction and Sonogashira Coupling reaction in water. The palladium-allyl complexes of such type of sulfonated NHCs are synthesized and they are better catalysts for Suzuki-Miyaura coupling reaction in water/alcohol mixture.

Diese Arbeit handelt von der Synthese und Charakterisierung von neuartigen, sulfonierten N-Heterozyklischen-Carbene Liganden in dessen stabiler Form. Diese Liganden wurden erfolgreich als in-situ Katalysatoren für Kreuzkupplungs-Reaktionen, wie beispielsweise Suzuki-Miyaura und Sonogashira, in Wasser eingesetzt. Die Palladium-Allyl Komplexe dieser sulfonierten NHC´s sind hergestellt worden und haben sich im Vergleich zu in-situ generierten Katalysatoren als bessere Katalysatoren für die Suzuki-Miyaura Kreuzkupplungs-Reaktion in Wasser / Alkohol Mischungen herausgestellt.
