@gdch.de Chemiedozententagung 2026 was exceptionally good. I am very happy to share our research activities. And Bulbasaur helped me a lot during presentation, serving as example of the synergy of two features (types). It was nice to meet old friends and make new ones.
This week, I attended 6th Anatolian Conference on Organic Chemistry in Antalya. And it was marvelous. Many thanks to the organisers @gloriusfrank.bsky.social Kevin Brown and Ramazan Altundaş, great job! Looking forward to the next edition of this conference. anatolianorgchem.org
First paper of the year is out! Take a look at our adventure to the configurational diversity of amidines in @orgchemfront.rsc.org. Great collaboration with the group of Prof. Tolstoy. pubs.rsc.org/en/content/a... #NMR #HydrogenBond

Outstanding work!
Excited to share the latest work from David Anderson just accepted @angewandtechemie.bsky.social on the structure and applications of #sodium #neopentyl a donor free #organosodium #reagent soluble in #hydrocarbon solvents @unibe.ch onlinelibrary.wiley.com/doi/epdf/10....
Beautiful structure!
The structure of unsolvated neopentyl sodium has been reported by @evaheviagroup.bsky.social in Angew. Chem., revealing a rare tetrameric motif. Combined with a Lewis base, it can metalate non-activated arenes and alkenes. 🔗 CSD Entry SAGDEO: dx.doi.org/10.5517/ccdc... #FeaturedStructureFriday
Absolutely magnificent lecture. Insight on how to properly apply computations to polar organometallics!

Today at the age of 86 my PhD supervisor Prof. Dr. Alexander Pozharskii passed away. Rest in peace dear friend, thank you for everything, your work will not be forgotten, and your legacy will live on forever in your students, and in the students of your students.
Check our new paper in @pubs.acs.org Inorganic Chemistry on how hydrogen bonding facilitates chalcogen exchange between arsine oxides and phosphine selenides. pubs.acs.org/doi/10.1021/... in Memoriam Prof. Dr. Lina M. Epstein (A.N.Nesmeyanov Institute of Organoelement Compounds RAS)
Hydrogen-Bond-Assisted Chalcogen Transfer between Phosphine Selenides and Arsine Oxides
The Brønsted acid catalysis is widely regarded as one of the most effective methods for activating inert substrates and enabling unique reactivity. In this work, we introduce the first example of H-bond-assisted chalcogen exchange between arsine oxides and phosphine selenides under mild conditions, providing a powerful approach to the synthesis of arsine selenides. The reaction proceeds successfully in both protic and aprotic solvents and is accelerated by the presence of any nonaqueous acid. This newly discovered reaction is tested for various arsine oxides R3AsO (R = Ph, Et, nBu, iPr) and phosphine selenides R3PSe (R = Ph, Me, Et, tBu) and overall demonstrates high conversion, although the use of reagents with bulky substituents significantly hinders its efficiency. The reaction mechanism involves the formation of a four-membered cyclic transition state, which requires overcoming steric and electrostatic repulsion, as well as significant distortion of the reagents’ tetrahedral geometry. Hydrogen bonding with the As═O fragment helps to reduce electrostatic repulsion between the P═Se and As═O groups, making the formation of the cyclic intermediate more favorable.

Very happy to have the opportunity to share our research at the Chemiedozententagung 2025
Interesting lecture by Alexander Antonov @alexanderantonov.bsky.social this morning on modulating #organolithium reactivity. At the #Chemiedozententagung #CDT2025.
Our new paper in @acs.org JOC on the Quadruple Reactivity of ortho-Dimethylaminoaryloximes. Check how non-covalent interactions allow precise control over reaction pathway with the usage of simple acids and solvents. pubs.acs.org/doi/10.1021/...
A Precise Synthetic Toolbox: H-Bond-Assisted Quadruple Reactivity of o-Dimethylaminoaryloximes
Non-covalent interactions are a highly promising tool for the development of transition-metal-free chemospecific synthetic transformations. Here, we demonstrate the implementation of non-covalent interactions as a simple, precise, and flexible synthetic toolbox, allowing the controlled transformation of o-dimethylaminoaryloximes into nitriles and hard-to-reach nitrogen heterocycles under mild conditions. This diverse reactivity is activated via hydrogen bonding and facilitated via the “buttressing effect” of the substituents next to the NMe2 group. All transformations require only simple and easily available acids and solvents, which generally provide precise control over the direction of the reaction, allowing the selective synthesis of nitriles, fused pyrazoles, isoxazoles, and pyrroles.
