Functional and Network PHAs via Stereoselective Polymerization and Tailored Post‐Transformation

Angewandte Chemie, EarlyView.
Catalyst‐controlled stereoselective (co)polymerization of functionalized lactones produces vinyl‐, allyl‐, and propargyl‐functionalized PHAs with high syndiotacticity and a broad applicable temperature window, which can be further transformed into crosslinked PHA thermosets, elastic supramolecular networks, and functional grafts.

Katalytische C–F‐Aktivierung bei Raumtemperatur: Enolat Kreuzkupplungen ermöglicht durch [Pd(1‐MeNAP)TFA]2 / LiHMDS

Angewandte Chemie, EarlyView.
Katalysatoren, die aus dem Trifluoroacetat‐verbrückten Methylnaphthyl‐Palladium‐Dimer [Pd(1‐MeNAP)TFA]2 und Biarylphosphin‐Liganden generiert werden, in Kombination mit der Base LiHMDS, fördern α‐Arylierungsreaktionen verschiedener Enolate mit nicht‐aktivierten Arylfluoriden bei Raumtemperatur.

Taming a Blue Gas—Structure and Chemistry of Hexafluorothioacetone

Angewandte Chemie International Edition, EarlyView.
Hexafluorothioacetone (1), a blue gas at r.t., was synthesized by flash vacuum pyrolysis of its cyclic dimer at 660°C. We discuss fundamental properties of elusive 1, including single‐crystal structure and nuclear magnetic resonance spectroscopy, despite its tendency to dimerize even at –74°C.

Unified Synthesis of Unconventional α‐Polyhalogenated Amines Through Hydroaminoalkylation

Angewandte Chemie International Edition, EarlyView.
A unified, redox‐neutral method that transforms alkenes and alkynes into α‐polyhalomethyl amines using stable hemiaminal reagents is reported. This approach enables access to CF3, CF2H, CF2Cl, and CFClH motifs, expanding halogenated amine space with broad substrate scope, functional group tolerance, and applicability to late‐stage modification of drug ...
