| Summary: |
Within this dissertation neutral carbene-, vinylidene- and allenylidene-complexes with bispyrazolylacetato-ligands have been synthesized and characterized. Nearly all complexed showed very high stability toward oxygen and water. For the benzylidene-complexes activity as catalysts in ring closing metathesis reaction was found. Issues concerning structural isomerism were investigated using two-dimensional NMR-experiments and X-ray structure analyses. Mechanistic explorations were supported by DFT-calculations.

| Summary in another language: |
Im Rahmen der vorliegenden Dissertation wurden neutrale Carben-, Vinyliden- und Allenyliden-Komplexe mit Bispyrazolylacetato-Liganden synthetisiert und charakterisiert. Die erhaltenen Komplexe wiesen fast durchgängig eine für Organometallverbindungen sehr hohe Stabilität gegenüber Sauerstoff und Wasser auf. Für die Benzyliden-Komplexe wurde Aktivität als Katalysatoren in der Ringschlussmetathese gefunden. Fragen zur strukturellen Isomerie wurden mittels zweidimensionaler NMR-Experimente und Röntgenstrukturanalysen untersucht. Mechanistische Untersuchungen wurden durch DFT-Rechnungen unterstützt.
