Phosphine-Catalyzed [4 + 3] Annulation of β′-Acetoxy Allenoates with 1C,3N-Dinucleophiles: Access to Functionalized Azepine Derivatives

A novel method for the synthesis of functionalized azepine derivatives has been developed through a phosphine-catalyzed [4 + 3] annulation of β′-acetoxy allenoates with benzimidazole-derived 1C,3N-dinucleophiles.

Photoswitchable Ambiphilicity: Light‐Gated Frustrated Lewis Pair Reactivity and Z‐Type Interaction

Angewandte Chemie, EarlyView.
Light‐controlled ambiphilicity is realized in photoswitchable intramolecular phosphorus/boron Lewis pairs. Reversible switching modulates both the thermodynamics and kinetics of frustrated Lewis‐pair reactivity, enabling light‐gated CO2 binding and release.

Aktivierung von Metallkomplexen durch Ultraschallwellen für eine gezielte Krebstherapie

Angewandte Chemie, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

Photochemical Oxygen‐Atom‐Transfer Reactivity of Platinum(II) Peroxycarbonates

Angewandte Chemie, EarlyView.
The coordination chemistry of metal–peroxycarbonate complexes (M(CO4)) remains poorly understood, with no reported studies of the photochemical reactivity of M(CO4) complexes. The platinum(II) peroxycarbonate complexes Pt(PPh3)2(CO4) and Pt(dppe)(CO4) (dppe = 1,2‐bis(diphenylphosphino)ethane) have been structurally characterized and are shown to ...

Borankatalysierte Dehydrierung von Wasser an Dioxaphospholen und ‐phospholanen

Angewandte Chemie, EarlyView.
Die borankatalysierte Dehydrierung von Phenylphosphinatestern, die aus der Reaktion von Dioxaphospholen und ‐phospholanen mit Wasser oder Luftfeuchtigkeit unter milden Bedingungen gebildet werden, wird beschrieben. Der Mechanismus dieser Umwandlung wurde durch kinetische Messungen und DFT‐Rechnungen untersucht, die auf die Wasserstofffreisetzung aus ...

Engineering Atomically Precise Cu4I4 Nanoclusters With Integrated Adsorption and Hydrogenation Functions for Efficient Photocatalytic Nitrate‐to‐Ammonia Conversion

Angewandte Chemie, EarlyView.
Efficient photocatalytic nitrate‐to‐ammonia conversion is achieved over an atomically precise Cu4I4 motif through dual‐site cooperation. Lewis‐acidic Cu centers promote nitrate adsorption and activation, while adjacent I sites facilitate active hydrogen generation for stepwise hydrogenation.
