CRC1333 – Project B05
Copper hydrides are widely used catalyst in different reactions such as CO2 hydrogenation, hydrosilylation, and hydroboration. For that purpose, we are trying to synthesize a mononuclear Cu-H complexes in Lewis acidic mesoporous materials such as covalent organic frameworks (COFs) or mesoporous metal oxides and investigate the effect of confinement on activity and selectivity for gas-phase CO2 hydrogenation.

Cu-catalyzed atom transfer radical addition reactions (ATRA) enable the versatile functionalization of alkenes and the simple synthesis of functionalized lactones and lactams. However, their disadvantage is that they often require high catalyst loadings, which makes them unsuitable for industrial processes. Polymerization reactions are a special case in which tailor-made polymers can be produced with low catalyst loading.
Since the redox process between Cu(I) and Cu(II) is reversible, it is possible to regenerate deactivated catalysts after the reaction if they can be separated intact and cleanly from the reaction mixture. This is made possible by immobilized catalysts, which are therefore an important tool for making ATRA reactions more sustainable and efficient

CRC1333 – Project B08 – Probing Confinement Enhanced Precatalyst Association in Pd Catalyzed Enyne Cycloisomerizations by Advanced NMR Spectroscopy
We are investigating and synthesizing platinum and palladium hydrides for enhanced catalytic reactions, particularly (enantio-)selective enyne cycloisomerization. This investigation aims to enhance reactions through innovative catalyst immobilization, fostering deeper mechanistic understanding.

Surface chemistry on catalysts is a complex process in which many parameters influence the kinetics and selectivity. By using hydride complexes, we aim to model hydrogen spillover from known catalyst systems to gain a deeper understanding and improve these systems.
