Proximity Engineering of Fe‒N4 Twins for Oriented Generation of Singlet Oxygen for Hospital Wastewater Treatment

Angewandte Chemie, EarlyView.
Precise modulation of Fe–N4 site distances constructs spin‐regulated Fe–N4 twins, triggering a volcano‐type Fenton‐like activity and promoting oriented singlet oxygen generation. The twin‐site catalyst enables highly selective and efficient hospital wastewater purification with simultaneous pharmaceutical degradation and disinfection under low ...

Arylhydrazines: Convenient Homogeneous Reductants for Scalable Cross‐Coupling

Angewandte Chemie, EarlyView.
Reductive cross‐couplings enable efficient C–C bond formation but are limited by the heterogeneity of Zn or costly reagents like TDAE. We report arylhydrazines as inexpensive, convenient reductants for Ni‐catalyzed sp2–sp3 coupling of aryl halides and secondary alkyl iodides. Mechanistic studies support hydrazine‐mediated NiII reduction for a NiI/NiIII

Surface Avidity of Anionic Polypeptide Coatings on Layer‐by‐Layer Nanoparticles Target Cancer‐Associated Amino Acid Transporters

Angewandte Chemie International Edition, EarlyView.
Electrostatically layered nanoparticles (NPs) coated with anionic polypeptides selectively target cancer cells by engaging amino acid transporters. Poly(L‐glutamate) (PLE) coatings cluster the glutamine transporter SLC1A5, prolonging NP surface retention, while poly(L‐aspartate) (PLD) coatings also bind SLC1A3, potentially promoting faster ...

Synthesis and Characterization of Unusual S=1 Fe(0)‐Silyl Complexes Supported by Styrene Ligands

Angewandte Chemie International Edition, EarlyView.
Despite the long‐standing importance of iron‐silicon bonds as related to catalysis, high‐spin Fe(0)‐silyl complexes remain a historical synthetic challenge in the field. Herein, we report the first series of high‐spin S = 1, styrene‐stabilized Fe(0)‐silyl complexes followed by extensive characterization via Mössbauer spectroscopy, single crystal X‐ray ...

A Crystalline Mono‐Coordinate Indium(I)‐Phosphaalkenyl

Angewandte Chemie International Edition, EarlyView.
The redox neutral carbometallation of a phospha‐alkyne using the dimeric indium(I) compound (InTer)2 is reported. This reaction affords a mono‐coordinate indium(I) compound that can reversibly extrude the phospha‐alkyne upon addition of a Lewis acid. Abstract The synthesis of the mono‐coordinate indium(I) compound In[C(Ad)═PTer] (Ad = 1‐adamantyl, Ter =

Programmable Nanoscale Motion via Molecular Patterning on DNA Origami

Angewandte Chemie International Edition, EarlyView.
DNA origami nanorods enable precise urease placement with tunable coverage and asymmetry, revealing that propulsion depends on a balance of catalytic loading and geometry. Maximum speed occurs at ∼25% end‐coverage and declines as enzyme distribution becomes more symmetrical.
