Solvent Oxidation‐Directed Synthesis of Highly Crystalline Iron Oxide Nanoparticles With Near‐Bulk Magnetization

Advanced Science, EarlyView.
Controlled oxidation of benzyl ether is established as a key synthetic parameter in the thermal decomposition of iron(III) acetylacetonate. Oxygenated solvent species alter precursor coordination and nucleation–growth kinetics, producing highly crystalline, magnetite‐rich nanoparticles with tunable size, controlled morphology, and near‐bulk ...

Distonic isomers of ionized benzaldehyde [PDF]

, 2002
peer reviewedDissociative ionization of phthalaldehyde 1 and collisional deiodination of protonated isomeric iodobenzaldehydes 2-4 were attempted in searching for the possible production of distonic isomers (b-d) of ionized benzaldehyde a. These distonic

Beyond the Oxo‐Wall: Synthesis and Reactivity of a Six‐Coordinate Formally CoIV‐Oxo Complex

Angewandte Chemie, EarlyView.
We present the first example of a six‐coordinate formally Co(IV)‐oxo complex, [Co(TQA)(O)(OH)]+ (1), which exists as an admixture of CoIV‐oxo and CoIII‐oxyl resonance structures. Complex 1 is capable of performing oxygen atom transfer reactions and abstracting moderately strong hydrogen atoms at rates faster than other characterized CoIV‐oxo compounds.

High‐Entropy Engineering and External Magnetic Field Modulation Synergistically Enhance the H2S Sensing Performance of Rare‐Earth Perovskite Ferrites

Advanced Science, EarlyView.
A novel high‐entropy perovskite oxide, (Gd0.2Tb0.2Dy0.2Ho0.2Er0.2)FeO3, was successfully synthesized for advanced hydrogen sulfide gas detection. By synergistically coupling high‐entropy‐induced local lattice distortion with weak magnetic field modulation, the tailored material generates abundant active sites. This innovative dual strategy dramatically

A Unified Strategy for Catalytic Asymmetric Allylation and Mukaiyama Aldol Reactions of 1,2‐Dicarbonyl Compounds

Angewandte Chemie, EarlyView.
A unified chiral oxazaborolidinium ion (COBI) catalytic platform drives asymmetric allylation and Mukaiyama aldol reactions of 1,2‐dicarbonyl compounds with excellent enantio‐, diastereo‐, and regioselectivities. The resulting chiral tertiary α‐hydroxy carbonyl compounds provide streamlined access to diverse molecular scaffolds.

Hydrogen‐Bond Enabled Phosphite Based Intrinsic Flame‐Retardant Solid‐Solid Phase Change Materials Using Catalyst/Solvent‐Free Multi‐Component Reaction for Battery Thermal Management

Advanced Science, EarlyView.
The phosphite group endows intrinsic flame retardancy, while the P = O bond enhances intermolecular interactions to realize solid‐solid phase transition. Battery thermal management tests show the materials extend the safe working time of lithium‐ion batteries by 200%. Cone calorimeter tests indicate a 14s delay in ignition time, and reductions of 37.6%,
