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 ...

Biosynthesis of the Fully Saturated C16 Homosesquiterpene Descartane Through Deprotonation With Cyclopropanation

Angewandte Chemie International Edition, EarlyView.
A non‐canonical C16 sesquiterpene synthase from Morganella morganii produces the unusual scaffold descartane. Its cyclisation mechanism was rationalised by isotopic labelling experiments and DFT calculations. Site‐directed mutagenesis altered enzyme function, resulting in alternative products, including voltairene, which requires a different ...
