Fluoroalkylcopper(I) Complexes Generated by the Carbocupration of Tetrafluoroethylene:
Construction of a Tetrafluoroethylene-Bridging Structure.
J. Am. Chem. Soc. 2014;
136: 15158-15161
Key words
copper - tetrafluoroethylene - aryl groups
Significance
The authors report the synthesis, characterization, and synthetic application of 2-aryl-1,1,2,2-tetrafluoroethylcopper
complexes. Starting with a carbocupration of tetrafluoroethylene (TFE), a variety
of 1,2-difunctionalized 1,1,2,2-tetrafluoroethanes were prepared in high yields.
Comment
The molecular structure of the aryl–TFE–copper species was determined by X-ray crystallography
and NMR analysis. Furthermore, the synthetic utility for liquid-crystalline compounds
bearing a tetrafluoroethylene-bridging structure was demonstrated.
