Photocatalysis Enables Chemodivergent Radical Polar Crossover: Ritter‐Type Amidation vs Heck‐Type Olefin Carbofunctionalizations

open access: yesChemistry – A European Journal, EarlyView.
One aryl makes the difference: switching styrenes with 1,1‐diaryl olefins as radical acceptors, the benzylic cation intermediate fate changes from Ritter‐type carboamidation to Heck‐type reaction. The decarboxylative photocatalytic chemodivergent methodology enabled broad scope and efficient scalability in both batch and flow.

Investigation of the Degree of Functionalization and Colloidal Stability of Shell‐by‐Shell Functionalized TiO2 Nanoparticles as a Function of Different Phosphonic Acid Chain Lengths

open access: yesChemistry – A European Journal, EarlyView.
The Shell‐by‐Shell structures of TiO2 nanoparticles, phosphonic acids (PAs) and sodium dodecylbenzenesulfonate (SDBS) in their solid and colloidal state were studied by thermogravimetric analysis and analytical ultracentrifugation. This combination showed that agglomerates were formed whose size depended on the PA chain length. This allowed conclusions

N,N‐Bis(trifluoromethyl)aminoacetonitrile: A Versatile Building Block for the Introduction of the Bis(trifluoromethyl)amino Group

open access: yesChemistry – A European Journal, Accepted Article.
N,N‐Bis(trifluoromethyl)aminoacetonitrile (CF3)2NCH2CN (1) that is accessible via a simple single‐step protocol is establish­ed as building block for the introduction of the (CF3)2N group. The two reaction sites of 1, the methylene unit and the nitrile (cyano) group, provide access to different organic substance classes.
