Studien zur Acidität und katalytischen Aktivität ungewöhnlicher LEWIS-Säuren

In dieser Arbeit wurde die Möglichkeit untersucht, die Acidität verschiedener Lewis-Säuren durch NMR-spektroskopische Methoden zu bestimmen. Carbokationen, Silyliumionen, Thioharnstoffe und Lewis-Säure aktivierte Lewis-Säuren waren die hauptsächlich untersuchten Klassen. Weiterhin wurde der Zusamme...

Table of Contents: The aim of this thesis was to probe the possibility to quantify the acidity of various classes of Lewis acids by NMR spectroscopic methods. Carbocations, silyliumions, thioureas, as well as Lewis acid assisted Lewis acids were among the investigated classes. Furthermore, a relationship between the experimentally quantified acidities and the catalytic activities of the Lewis acids in simple Diels-Alder reactions was investigated. Thereby, acidity-activity relationships were found and class specific questions could be answered.
