AutoGCA—A Software Tool for the Automated Analysis of Gas Chromatograms

Chemie Ingenieur Technik, EarlyView.
The automation of tedious manual or semi‐automated analysis of gas chromatograms offers significant time savings in analytical chemistry. An automated approach is proposed that works even for gas chromatography datasets with highly overlapping or baseline distorted peaks. ABSTRACT Gas chromatography (GC) is an important tool in analytical chemistry and

Remote Migratory Reductive Arylation of Unactivated Alkenes Enabled by Electrochemical Nickel Catalysis

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
we have developed an electrochemical Ni−H catalyzed arylation coupling method of unactivated alkenes with aryl halides. The method displays broad functional group tolerance and proceeds under very mild conditions. Furthermore, aryl chlorides were also compatible substrates in this catalytic system. This conversion holds significant implications for the

Next‐Generation Carbon‐Based Anodes for Alkali Metal‐Ion Batteries: Recent Progress on Biphenylene and Emerging Materials

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Recent advances in carbon‐based anodes for alkali metal‐ion batteries are critically reviewed, with emphasis on biphenylene and other emerging carbon allotropes. Biphenylene exhibits exceptional theoretical electrochemical properties beyond conventional graphite, highlighting its strong potential as a next‐generation anode material once scalable ...

The Serendipitous Discovery of Rollover Cyclometalation: From Unrecognized Observation to Transformative Chemistry

European Journal of Inorganic Chemistry, EarlyView.
Rollover cyclometalation is a distinctive variant of classical cyclometalation where a chelated heterocyclic ligand undergoes internal rotation, releasing one donor atom from coordination and subsequently activating a remote C─H bond with high regioselectivity.

Efficient Synthesis of Cannabinoid Acids

European Journal of Organic Chemistry, EarlyView.
In this study, an alternative synthesis of cannabinoid acids was developed based on an O→C acyl rearrangement. Specifically, this strategy involved regioselective bromination followed by halogen–lithium exchange and intramolecular nucleophilic addition, which led to successful carboxylation.

Fluorinated Iminosugar Glycomimetics: Synthesis and Activity as GCase Ligands

European Journal of Organic Chemistry, EarlyView.
DAST‐mediated deoxyfluorination of suitably functionalized piperidines provided regio‐ and stereoselective access to fluorinated piperidine and pyrrolidine glycomimetics, the latter arising from an unusual ring‐contraction process. Fluorination generally enhanced β‐glucocerebrosidase (GCase) inhibitory potency, but lost PC activity toward L444P/L444P ...

Transition Metal‐Free C(sp2)─Ge Bond Construction and Downstream Functionalization

European Journal of Organic Chemistry, EarlyView.
Organogermanes combine the advantages of other tetrels such as silicon or tin without their respective downsides in terms of stability and reactivity. This Perspective describes both the transition metal‐free formation of C(sp2)─Ge bonds and the subsequent functionalizative degermylation reactions to access organic compounds of interest.

Control of Aryne Capture Regioselectivity via Fluoroboronate-induced Distortion

, 2019
Arynes are valued as extremely versatile electrophilic intermediates. Control over the regioselectivity with which arynes react is typically achieved using comparatively simple and/or chemically inutile substituents close to the reactive triple bond ...

Photocatalyst‐Free Trifluoromethylation of Indolizines Through an Electron Donor–Acceptor Complex

European Journal of Organic Chemistry, EarlyView.
A new photocatalyst‐free pathway for the direct C‐3‐trifluoromethylation of indolizines and imidazo[1,2‐a]pyridines through an electron donor–acceptor (EDA) complex is studied. This regioselective reaction supports a wide range of functional groups, indicating good versatility and robustness.
