We investigate different aspects of the coordination chemistry of early and late transition metal complexes in homogeneous catalysis. Starting from well-defined molecular systems, reaction optimisations and studies of the selectivity and kinetics of product formation are performed. Based on synthetic organometallic chemistry we aim for a fundamental understanding of structure-activity relationships. Research interests in our group range from the realization of unusual coordination environments in early transition metal complexes, activation of small molecules (e.g. H2O, H2, N2, CO2, olefins, alkynes, amine-boranes) to the development and catalytic evaluation of new pincer complexes of late transition metals and the mechanistic and kinetic investigation of homogenously catalysed reactions.
Our recent research efforts in the fields of catalytic (asymmetric) hydrogenation led to numerous successful cooperations with academic and industrial partners that were devoted to the selective synthesis of pharmaceutically relevant building blocks and APIs. Building on this expertise, we became interested in the application of mechanochemistry for monitoring the stability and degradation profiles of APIs. Within the interdisciplinary project PHARMSAF, funded by the Leibniz Association, we aim to develop a predictive solid-state tool for improved pharmaceuticals safety.
