Homogeneous catalysis and mechanistic studies

The transition of chemical production to processes that are environmentally benign and sustainable is a big challenge for our society and for chemical research. Homogeneous catalysis can make a substantial contribution by developing processes that convert simple substrates into valuable products without using synthetic reagents in stoichiometric amounts or large amounts of energy. The development of such processes is the prime goal of our research group.

Oxidative Coupling Reactions

The activation of C-H bonds is an important goal in chemical research. The direct substitution of hydrogen in C-H bonds by a desired fragment creates interesting synthetic alternatives to the more common multi-step approach of first introducing reactive functional groups. Instead, only one step is needed and very simple substrates can be used, as C-H bonds are ubiquitous in organic compounds. Oxidative coupling reactions can achieve such transformations by utilizing an oxidant and a catalyst.

In our group, we focus on the development of such reactions under mild and sustainable conditions, i.e., preferably by using elemental oxygen or simple peroxides as oxidant.

We are also developing other methods for direct and atom economic organic syntheses, for example to access starting materials for our projects or to apply strategies that were inspired by our mechanistic studies. In collaboration with the Junkers group, our method of acid-induced radical formation was also applied to polymerization reactions at ambient temperature (Macromolecules 2016, 49, 4124-4135).

Mechanistic Studies

We are highly interested in investigating the mechanism of organic reactions. We study reactions developed in our own group, but also others and we are always interested in collaborations with other research groups. We use a variety of techniques, including synthetic, spectroscopic and kinetic studies (e.g., see J. Am. Chem. Soc. 2012, 134, 5317). To obtain kinetic data, we use NMR spectroscopy or reaction calorimetry. We like to evaluate the data by Donna Blackmond’s method of Reaction Progress Kinetic Analysis (e.g., see J. Org. Chem. 2014, 79, 12033). In collaboration with other scientists, we combine experimental with theoretical mechanistic studies (e.g., see Chem. Eur. J. 2015).
