The oxidation of alcohols, amines, and halides is a fundamental transformation in organic chemistry with significant applications in the synthesis of fine chemicals, pharmaceuticals, and natural products. Here we show that a broad variety of N‐heteroarenes bearing hydroxymethyl, aminomethyl, or halomethyl groups are oxidatively dehydrogenated to their ...

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.

Single GAF Domain Phytochrome Exhibits a pH‐Dependent Shunt on the Millisecond Timescale
During their light‐induced photocycle, phytochromes can engage in a thermal reversion back to the initially excited state, denoted as a shunt. This study investigates a pH‐dependent shunt transition in the Pfr state of the All2699g1 phytochrome from Nostoc punctiforme using UV/Vis laser flash photolysis and kinetic modeling. The findings suggest a keto‐

The properties of metal‐organic interfaces are important for the performance of organic electronic devices. The adsorption of alternant and non‐alternant polycyclic conjugated hydrocarbons on Cu(111) was modeled using first‐principle DFT calculations. The difference in interface properties between physisorption and chemisorption is shown and relations ...

The combination of continuous flow technology and visible light photocatalysis has been used to improve the safety and productivity of reactions with diazonium salts as reactive intermediates. This approach has proven to be a reliable method for various organic synthesis routes with diazonium salts under mild and well‐defined conditions.

Physics‐based inverse modeling of battery degradation with Bayesian methods
To further improve Lithium‐ion batteries (LiBs), a profound understanding of complex battery processes is crucial. Physical models offer understanding but are difficult to validate and parameterize. Therefore, automated machine‐learning methods (ML) are necessary to evaluate models with experimental data. Bayesian methods, e.g., Expectation Propagation

En Route Toward Sustainable Polycarbonates Via Large Cyclic Carbonates
This review reports an up‐to‐date overview of the synthetic methodologies developed for the preparation of large cyclic organic carbonates with ≥ 6‐membered rings (6M‐CCs and above), highlighting the most sustainable synthetic pathways employing diols (including renewable‐based ones) and non‐hazardous carbonyl sources, e.g., linear organic carbonates ...
