We are hiring again, please share, thanks! PS: Applications (including a short research proposal) only via our university's online system please.

Ich wollte das erst später posten. Doch die Meldungen der letzten Tage zu nahen Kippvorgängen im Erdsystem nebst globaler Abkehr von einst etablierter Rationalität gibt nun tragischen Anlass. Ab 7.5. ist im Kino zu sehen, wie drei Akteure aus den Wissenschaften mit alldem umgehen. #DasGewichtDerWelt

We are hiring! Please spread, thanks! PS: Note that all applications have to go through our university's new online portal, see link in the pdf.

Almost a double-header! Last Friday and this Monday Dhananjoy and Christoph defended their theses, with great success. Thank you for your contributions and all the best to both of you!

Start of RESOLV’s third funding period With the beginning of the new year, the Cluster of Excellence RESOLV has officially started its third funding period (2026 to 2032) with new Research Areas. Learn more about our new Research Areas: www.solvation.de/research #SolvationScience

Chiral control through halogen bonding could be the next frontier for organocatalysis – allow Victoria Atkinson to guide you through the hisory, complexities and exciting new prospects on the horizon.

Congratulations to the Bach group (@bach-lab.bsky.social) for this very nice Co-catalyzed asymmetric C-H alkylation, to which we contributed a few DFT calculations: pubs.acs.org/doi/10.1021/...

Enantioselective Intramolecular C–H Alkylation Catalyzed by a Nonsymmetric Chiral Cobalt Porphyrin

Upon catalysis (1 mol %) by a chiral cobalt porphyrin, quinazolinones with a tethered diazo alkane precursor underwent an enantioselective C–H alkylation at carbon atom C4. Formation of five-, six-, a...

Just as chemists harness hydrogen bonds when designing organocatalysts, researchers have started using halogen bonds to promote a variety of reactions.

In November, we welcomed Lisa-Marie as a new PhD student. She will tackle some carborane-based halogen bond donors. All the best!

During our investigation on multidentate ortho-carborane-based halogen bond donors, we noticed that they from very interesting co-crystals with halides.

Ortho‐Carborane‐Derived Halogen‐Bonded Sandwich Complexes

A systematic co-crystallization-study of a tridentate ortho-carborane-based halogen-bond donor with halides was performed. Several association complexes are evaluated to give further insights into th....

Anyway, we need some joy, so here's the Egyptian foreign minister being given a Lego Pyramid by the Danish foreign minister.

Just like halogen bonding, chalcogen bonding is not purely electrostatic - orbital interactions are also very important and my override the electrostatics. We recently published an illustrative example for this: inter-anion chalcogen bonding. See: pubs.rsc.org/en/Content/A...

Prof. Wolfgang Kirmse, former Chair of Organic Chemistry II at Ruhr-University Bochum, has died on October 3rd. He was known, inter alia, for many fundamental contributions to carbocation chemistry and was a very well-visible representative of our chemistry department for a long time. Rest in peace.

Please check this announcement for an early-career group leader, hosted jointly by our cluster of excellence RESOLV and the MPI Kofo. The thematic focus should be on catalysis: jobs.ruhr-uni-bochum.de/jobposting/4...

In a preprint, we report a particularly interesting substrate for biaxial halogen bonding with iodine(III)-based Lewis acids: allenes. We also introduce chiral variants which allow enantiodiscrimination of allenes via NMR:

At the end of August, we said goodbye to Julian Wolf, former PhD student and postdoc. Thanks a lot for your contributions, particularly all the work to establish highly enantioselective XB catalysis, and all the best!

Wow. Check this out. Politicians actually trying to solve problems can achieve a lot! www.washingtonpost.com/climate-solu...

Paris said au revoir to cars. Air pollution maps reveal a dramatic change.

Air pollution fell substantially as the city restricted car traffic and made way for parks and bike lanes.
