Stereoselective Synthesis of Alkenyl Fluorides and Alkynes by Defluoro Coupling of Trifluoromethyl Arenes

Angewandte Chemie, EarlyView.
A practical, stereoselective method for synthesizing tri‐ and tetra‐substituted 1,2‐fluoro‐borylalkenes and alkynes via defluorinative C–C coupling of CF3–arenes with organodiboron reagents is reported. Enabled by a Lewis base activator, products are formed in up to 94% yield and >98:2 Z/E selectivity.

Arene‐Ruthenium(II)‐Carboxylate für C–H‐Alkylierungen und Arylierungen bei Annährend Raumtemperatur

Angewandte Chemie, EarlyView.
Es wurde vermutet, dass die Aktivität von Aren‐Ruthenium‐Katalysatoren bei der C–H‐Aktivierung von hohen Reaktionstemperaturen abhängt. Im Gegensatz dazu zeigen wir eine Aren‐Ruthenium‐katalysierte C–H‐Aktivierung bei annährender Raumtemperatur. Zusammenfassung Das langjährige Streben nach effizienteren Katalysatoren hat die Entwicklung von C–H ...

Inverting the Circularly Polarized Luminescence Handedness of Chiral Supramolecular Polymers Using Temperature

Angewandte Chemie, EarlyView.
The supramolecular polymerization of enantiopure triarylamine trisamide monomers bearing aggregation‐induced emissive tetraphenylethene units, gave rise to a strong circularly polarized luminescence (with glum values as high as |1.8·10−2|). Strikingly, upon fast versus slow cooling rates, these monomers formed distinct hierarchical self‐assemblies (i.e.

Modular Synthesis of Pyritide‐Inspired Macrocycles Featuring Bipyridine Motifs

Angewandte Chemie, EarlyView.
A pyritide‐inspired build/couple/pair strategy yields a diverse macrocycle library. This approach expands chemical space and enables the discovery of 6paW, a potent anti‐ferroptotic agent. Abstract Macrocycles represent a promising class of drug‐like scaffolds with unique structural features and the ability to engage challenging targets such as protein–

Efficient Synthesis of Narrowly Dispersed Brush Polymers via Living Ring-Opening Metathesis Polymerization of Macromonomers [PDF]

, 2009
Various macromonomers (MMs) were efficiently synthesized through the copper-catalyzed “click” coupling of a norbornene moiety to the chain end of poly(methylacrylate), poly(t-butylacrylate), and polystyrene that were prepared using atom transfer radical ...
