Aza‐Diphosphazenanes: Inorganic Cyclohexane‐like Connectors with Stereochemically Tunable Exit Vectors for Molecular and Macromolecular Chemistry

Angewandte Chemie, EarlyView.
New aza‐diphosphinanes have been prepared and a model has been developed to explain their cis/trans isomerization. Two‐fold oxidation leads to new aza‐diphosphazenanes as robust inorganic connectors with selectable stereochemistry. Polycondensation reactions results in the first inorganic cyclo‐linear polyphosphazenes which have high‐molecular weights ...

Base‐Catalyzed Remote Hydrogermylation of Olefins

Angewandte Chemie, EarlyView.
This study presents the first remote hydrogermylation of alkenes, utilizing a rare base‐catalyzed strategy in the absence of transition metal catalysts. The methodology is operationally simple and highly versatile, enabling up to 8‐carbon chain walks.

B ← N Lewis Pair Fusion of N,N‐Diaryldihydrophenazines: Effect on Structural, Electronic, and Emissive Properties

Angewandte Chemie, EarlyView.
B─N Lewis pair fusion of N,N‐dipyridyldihydrophenazine and its benzofused homologs results in steric constraints that enforce a bent structure in both the ground and excited states, reduces the antiaromatic character of the central dihydropyrazine heterocycle and promotes a quinoidal resonance structure, bathochromically shifts the absorption and ...

Discovery and Biosynthesis of Celluxanthenes, Antibacterial Arylpolyene Alkaloids From Diverse Cellulose‐Degrading Anaerobic Bacteria

Angewandte Chemie, EarlyView.
The structure and biosynthetic origin of the enigmatic “yellow affinity substance” (YAS) from the anaerobe thermophile Clostridium thermocellum (now: Acetivibrio thermocellus) were elucidated. YAS is a complex of unusual antibacterial arylpolyene alkaloids (celluxanthenes) that are produced by various cellulolytic anaerobes.
