What we do

Our group is home to the development of new organic reactions, that maximally rise the complexity of simple organic molecules in a single synthetic operation. This is typically achieved by guiding the starting material(s) through a sequence of transformative elementary steps. Evidently, the outcome of such a sequence heavily relies on the nature of the reactive intermediates encountered along the way. Most research in the area engages transition metal catalysts to generate these reactive intermediates. In a complementary approach, we try to identify and understand species that provide highly interesting reactivity and do not require a transition metal catalyst for their formation or follow up chemistry. Our current focus is on vinyl cations and boryl anions.

If you are a student at whatever stage of your studies and got interested in our work, please stop by @ our laboratories or email us to learn more about research opportunities for your bachelor/master thesis or your "Forschungspraktikum" in our group.

Research

Rearrangement sequences and domino/cascade reactions are ideal transformations for rising the complexity of simple organic molecules in a single synthetic operation. To efficiently realize these reaction types we engage high-energy reactive intermediates such as vinyl cations and boryl anions. As both of these species are still underdeveloped and poorly understood, all of our experimental work is accompanied by mechanistic analysis such as control experiments, time resolved NMR-spectroscopy and DFT based computational methods.
