Catalytic hydroboration: a study of model hydridoiridium and hydridorhodium boron complexes
… dissociation was responsible for opening up the vacant coordination site on the complex and thus providing for acetylene coordination. When the chloride ligand on <B>II</B> was replaced with other Lewis bases, the reactivity towards trimethylsiliylacetylene was qualitatively determined to be …

Polymerization of olefins and functionalized monomers with zirconocene catalysts
… of such catalyst systems as single-site catalysts is an oversimplification. In zirconocene/MAO systems, more than one active species is present under the applied reaction conditions, which may cause bimodal MWD of the obtained polymers. It is concluded that if the active species are …

Investigations into cyclopropanation and ethylene polymerization via salicylaldiminato copper (II) complexes
Two distinct overall research objectives are in this Master’s thesis. Very little relates the two chapters apart from the ligands. The first chapter addresses diastereoselective homogeneous copper catalyzed cyclopropanation reactions. Cyclopropanation of styrene and ethyl diazoacetate (EDA) is a …
