Platinum‐Catalysed Hydrofluorination of Alkynes at Room Temperature Promoted by a Fluoride Shuttle

Angewandte Chemie, EarlyView.
This work presents an air and moisture tolerant platinum‐catalysed hydrofluorination system that gives selectively (Z)‐fluoroalkenes. Experimental and computational investigation on the mechanism allowed for the identification of catalytic species. The hydrofluorination is mediated by complexes between the fluorinated anion and HF, resulting into BF3 ...

Intermolecular Sp3C─H Metalation of Non‐Nucleophilic Brønsted Bases Using Simple Lewis Acids

Angewandte Chemie, EarlyView.
Simple M2X6 Lewis acids (M═Al or Ga, X═Cl, Br or I) effect the sp3C─H metalation of a number of hindered bases, including the ubiquitous non‐nucleophilic 2,6‐ditertbutyl substituted pyridine/pyrimidines. Mechanistic studies indicate a frustrated Lewis pair mechanism requiring singly halide‐bridged super‐electrophilic M2X6 dimers for sufficiently low C ...

Feedstock‐Derived Thiophene Radical Anions Exhibiting Redox Stability at Extreme Potentials

Angewandte Chemie, EarlyView.
Although organic redox systems are emerging as next‐generation energy storage media, stability at high cell voltage is often achieved at the expense of synthetic accessibility. Here, we isolate and characterize a feedstock‐derived thiophene radical anion bearing simple ester groups.

C(sp2)─H Bond Activation with a Heterometallic Nickel–Aluminium Complex

Angewandte Chemie, EarlyView.
Despite the prevalence of Ni/Al catalysts for pyridine C─H functionalization, mechanistic details of such systems remain scarce. Herein, we present the discovery of PCy3‐catalyzed bond‐breaking and making processes that occur in the coordination sphere of a novel Ni─Al heterometallic complex.
