A Tert‐Alkyl Terephthalate Derivative as a Universal Degradable Unit for Condensation Polymers

Angewandte Chemie, EarlyView.
A sterically bulky dicarboxylic acid core bearing a tertiary alkyl ester enables photocatalytic C─O bond cleavage via generation of a stabilized tertiary alkyl radical. Incorporated into polyarylate, polyurethane, and polyester, this universal trigger facilitates efficient degradation under identical conditions (up to 99% within 2–4 h). Remarkably, the

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.

Axially Chiral Nonalternant Polycyclic Aromatic Hydrocarbon With Consecutive Pentagons Exhibiting Large Spin‐Polarized Current

Angewandte Chemie, EarlyView.
Here we report two nonalternant polycyclic aromatic hydrocarbons (PAH) (1 and 2), which contain two and four consecutive pentagons, respectively. Under acidic conditions, 1 and 2 dimerize to afford the axially chiral dimers AC1 and AC2. The central azulene moiety in both 2 and AC2 shows an unusually short transannular bond of 1.366 Å.

Deprotektive Alkylierung: Eine Plattform zur Umsetzung von Alkoholen zu Aminen mittels Nonafluormesitylensulfonamiden

Angewandte Chemie, EarlyView.
Die direkte Umwandlung von Alkoholen in tertiäre oder sekundäre Amine in einem Reaktionsschritt unter Verwendung von Nms‐Amiden wird beschrieben. Die Transformation zeichnet sich durch eine breite Toleranz gegenüber verschiedenen funktionellen Gruppen und eine hohe Stereospezifität aus, was ihre Eignung für die Synthese isotopenmarkierter Arzneimittel ...

Luminescence Vapochromism of a Cu(I)/Na Phosphane Iodide Assembly Based on a Secondary‐Sphere Sodium Response

Angewandte Chemie, EarlyView.
The luminescence of a heterometallic d‐s {Cu2I2Na2} phosphane‐phosphinate aggregate is regulated by an interplay of Na+–π/I– contacts and reversible coordination of oxygen‐containing organic molecules to Na ions. Structural variations caused by the incoming guest lead to a wide and selective variation of the emission color and illustrate a new approach
