The Challenging P‐Alkylation of Aromatic Phosphorus Heterocycles and Follow‐Up Reactions

ChemistryEurope, EarlyView.
P‐alkylation of λ3σ2‐phosphinines is hindered by weak nucleophilicity and scarce synthetic access, previously requiring multistep routes or extreme electrophiles. A direct ambient‐condition method is reported using 3,5‐bis(trimethylsilyl)‐phosphinine/B(C6F5)3 with esters or iso(thio)cyanates to generate stable 1‐R‐phosphininium salts.

Skeletal Editing from Pyridine to Aniline via C‐Insertion and N‐Isomerization

ChemistryEurope, EarlyView.
A concise protocol is presented that converts pyridines into anilines by externalizing the original pyridine nitrogen at either the "ipso" or "ortho" position, which results in para or meta‐primary aniline products. A key carbene‐insertion step precedes nitrogen migration, preserving both ring size and overall structure.

Regulating Interfacial Hydrogen‐Bonding Connectivity by Oxygen Vacancies‐Driven [Fe(CN)6]3− Coordination for Boosting Hydrogen Peroxide Electrosynthesis

Carbon Energy, EarlyView.
ABSTRACT The inherent hydroxide‐rich (OH⁻) environment in alkaline media facilitates the two‐electron oxygen reduction reaction (2e−ORR). However, the strong interaction between alkali metal cations and solvated water molecules significantly reduces the connectivity of the hydrogen bond network within the alkaline electric double layer, thereby ...

T½ Tuning in a Synergistic BODIPY‐Tetrazole Fe(II) Spin‐Crossover‐Photoluminescence System via Co‐Ligand Variation

Chemistry – A European Journal, EarlyView.
We report a modular spin crossover‐photoluminescence (SCO‐PL) system: heteroleptic, mononuclear Fe(II) coordination compounds bearing equatorial BODIPY fluorophores that exhibit synergistic PL response upon spin state switching. Exchanging apical nitrile co‐ligands tunes electronic and structural properties, giving precise control over the SCO and PL ...
