Would you like to learn about the photoconversion of 2-propanol on rutile titania? Then let RTG PhD student Jessica Kräuter tell you all about it in this new video!
The video shows the different setups which were used to analyze the investigated model reaction, which is of interest for chemical industries. It is based on a paper published earlier this year in collaboration with the Libuda group at the Friedrich-Alexander University Erlangen-Nürnberg.

The communication "Titanium-Catalyzed Intermolecular Hydroaminoalkylation of Alkenes with Tertiary Amines" by RTG PhD students Dennis Geik and Michael Rosien has just been accepted for publication in the journal Angewandte Chemie.
In the paper, catalytic intermolecular hydroaminoalkylation of alkenes with various tertiaryalkylamines and excellent regioselectivity at low temperatures is presented. The work was rated as "highly important (top 20%)" and even as "very important (top 5%)" by two of the reviewers, respectively. The paper is also featured in the "Hot Topic: C-H Activation" section of the Wiley online library.

The most recent paper by RTG PhD students Tobias Kaper and Dennis Geik was chosen for a cover feature in Chemistry - A European Journal!
The communication covers the conversion of alkynes into allylic amines within an unbelievably short reaction time of 4 hours, with broad scope, high yields, and excellent stereoselectivity to provide access to synthetically useful products. The paper is also featured in the "Hot Topic: C-H Activation" section of the Wiley online library.

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.

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 alumnus Gabriele Tomaschun, the authors employed amines as spectator molecules on Pt nanoparticles to achieve selective surface site activation in heterogeneous catalysis.

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"!

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.
Participation is free of charge.
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 University's Press & Communication department has published a new press release about the work of RTG member Prof. Dr. Ralf Rabus.
The group performs research on an extraordinary species of bacteria that degrade particularly stable organic compounds, without the need of oxygen. They thus represent a downright treasure chest for novel biochemical reactions, which could help in the remediation of polluted soils.
The scientific meeting "From the witches cauldrons in materials science" ("Aus den Hexenküchen der Materialwissenschaften") took place on April 29th and 30th, 2018 in Goslar. We were again able to win excellent female scientists as speakers for the conference. The meeting was held jointly by the Center of Interface Science and the Research Training Group "Chemical Bond Activation", and was also supported by the SFB 1083 "Structure and Dynamics of Internal Interfaces".
At the event, RTG PhD student Jessica Kräuter was awarded with the prize for the best poster. Congratulations!
The Deutsche Forschungsgemeinschaft has approved the establishment of a research training group (RTG) at the Carl von Ossietzky University Oldenburg. The DFG will support the project financially with ca. 3,5 million Euro, initially for a time period of 4,5 years.
Starting in October 2017, twelve PhD students will start their research on the topic of chemical bond activation.
