Cover Picture in ChemPhysChem

The article "Electronic Transitions in Different Redox States of Trinuclear 5,6,11,12,17,18-Hexaazatrinaphthylene-Bridged Titanium Complexes: Spectroelectrochemistry and Quantum Chemistry" by RTG alumnus Dr. Aleksandra Markovic and RTG PhD student Luca Gerhards was selected for a cover picture in ChemPhysChem!
In the publication, the trinuclear [(Cp2Ti)3HATN(Ph)6] complex was studied. Voltammetric analysis showed six 1e oxidations and three 1e reductions. First principle calculations on TDDFT and CASSCF levels were used show that the ground state is formed by spin states of different multiplicity, explaining the observed electronic transitions in the UV‐vis‐NIR ranges.

New Video

Earlier this year, the paper "Insights into Spectator-Directed Catalysis: CO Adsorption on Amine-Capped Platinum Nanoparticles on Oxide Supports" was published in ACS Applied Materials & Interfaces. In the publication, which was co-authored by RTG PhD alumni Gabriele Tomaschun, the authors employed amines as spectator molecules on Pt nanoparticles to achieve selective surface site activation in heterogeneous catalysis. If you want to learn more,  check out the new video above!

Cover Feature

This was definitely not a "Schnapsidee"! (Schnapsidee: German proverb that describes a silly or impractical idea, often occurring after one too many glasses of alcohol.)
The communication "Intermolecular Hydroaminoalkylation of Propadiene" from our RTG PhD students Tobias Kaper and Michael Warsitz was selected for a cover feature in the journal Chemistry - A European Journal. The cover shows how the simplest allene 1,3-propadiene is employed in intermolecular hydroaminoalkylation reactions with secondary amines to give the corresponding allylamines in high regioselectivities. The referees attributed great significance to the reported results - less than a fifth of the submitted manuscripts receive such a positive review. As such, the communication is listed as a "Hot Paper"!

You can find the cover here: https://doi.org/10.1002/chem.202004119
and the communication here: https://doi.org/10.1002/chem.202003484.

Women in Science and Industry 2020

The online event "Women in Science and Industry 2020" will take place on November 4th 2020, starting at 9:00. Female speakers from different chemistry-related fields will talk about their career paths, answer questions and provide tips for aspiring scientists.

For more information, please refer to the website https://uol.de/en/grk-2226/wsi.

Participation is free of charge.


New Cover Feature

The communication "Titanium‐Catalyzed Hydroaminoalkylation of Ethylene" from our RTG PhD students Michael Rosien and Iris Töben was selected for a cover feature in the renowned journal Chemistry - A European Journal! The cover shows a simplified titanium‐catalyzed hydroaminoalkylation reaction cycle of ethylene with secondary amines in front of the Oldenburg Palace.
The referees attributed great significance to the reported results - less than a fifth of the submitted manuscripts receive such a positive review.
