PhD Project: Synthesis of Cyclic Polycarbene Ligands and Their Metal Complexes

Abstract of Research Project

Over the last years N-heterocyclic carbenes (NHC) have become of interest as free molecules and as ligands for transition metal complexes. A huge variety of NHC complexes are known today. However, only a few examples for complexes with N-heterocyclic carbene ligands with a cyclic arrangement have been described.

My topic deals with the synthesis of macrocyclic polycarbene ligands and their metal complexes. In contrast to the established metal template directed syntheses for polycarbene ligands, which are limited to a few transition metals, the aim of the project is the development of a general synthesis for macrocyclic polycarbene ligands and their transition metal complexes starting from different azoles. For these purposes the key step is the synthesis of macrocyclic polyazolium salts, which can be used as precursors for the preparation of the desired compounds.
