From Berzelius to Hyperspace: Previously Unrecognized Network of Reactivity in Textbook Brominations

Angewandte Chemie, EarlyView.
Robotic scans across multidimensional condition spaces of classic bromination reactions uncover regions of previously unrecognized reactivity, yielding new major products and novel substitution patterns. Correlation and anticorrelation analyses of product distributions across these hyperspaces enable reconstruction of the underlying mechanistic ...

Erste Hinweise auf Ozonido‐TMC‐Komplexe von Eisen und Kobalt

Angewandte Chemie, EarlyView.
Die Umsetzung der Eisen(II)‐Komplexe [(TMC)Fe(OTf)]BArF und [(D12‐TMC)Fe(OTf)]BArF sowie der Kobalt(II)‐Komplexe [(TMC)Co(OTf)]BArF und [(D12‐TMC)Co(X)]BArF (X = OTf, F) mit Ozon führt in einem 4:1‐Gemisch aus 2‐Me‐THF und THF bei Temperaturen bis −155°C zur Bildung von Ozonido‐ und Oxido‐Komplexen.

Extracellular LCN2 Binding to 24p3R in Astrocytes Impedes α‐Synuclein Endocytosis in Parkinson's Disease

Advanced Science
The spread or transmission of pathologic α‐synuclein (α‐Syn) is emerging as potentially important driver of Parkinson's disease (PD) pathogenesis. Emerging evidence suggests that astrocytes play an important role in uptake/clearance of extracellular α ...

Natur"syn"

Tidsskriftet Antropologi, 1993
Metaforer kan vare bade oplysende og „formorkende“. Udtryk som „perspektiver pa naturen" eller „synspunkter pa naturen" virker ganske harmlose. „Det er jo bare talemader," siger vi. Alligevel former sadanne udtryk vores tankning, subtilt og ubemarket. Metaforer er oplysende, nar de letter vores tankning.

Unified Synthesis of Unconventional α‐Polyhalogenated Amines Through Hydroaminoalkylation

Angewandte Chemie International Edition, EarlyView.
A unified, redox‐neutral method that transforms alkenes and alkynes into α‐polyhalomethyl amines using stable hemiaminal reagents is reported. This approach enables access to CF3, CF2H, CF2Cl, and CFClH motifs, expanding halogenated amine space with broad substrate scope, functional group tolerance, and applicability to late‐stage modification of drug ...

First Evidence for Ozonido‐TMC Complexes of Iron and Cobalt

Angewandte Chemie International Edition, EarlyView.
Reaction of ozone with iron(II) complexes [(TMC)Fe(OTf)]BArF, [(D12‐TMC)Fe(OTf)]BArF, and cobalt(II) complexes [(TMC)Co(OTf)]BArF, [(D12‐TMC)Co(X)]BArF (X = OTf, F) gives ozonido and oxido complexes at temperatures as low as –155°C in a 4:1 mixture of 2‐Me‐THF and THF. ABSTRACT We present compelling evidence for the first Fe‐ and Co‐ozonido complexes: [

Syn‐Drift Plate Tectonics

Geophysical Research Letters
The paradigm of plate tectonics holds that ocean plates are rigid during drift and only experience tectonic deformation at subduction zones, but new findings from the Pacific challenge this idea.
