Cross-Coupling of [2-Aryl-1,1,2,2-tetrafluoroethyl](trimethyl)silanes with Aryl Halides
摘要:
The synthesis of arylCF(2)CF(2)SiMe(3) and their reactivity in cross-coupling reactions with aryl iodides and aryl bromides to afford a range of 1,1,2,2-tetrafluoro-1,2-aryl-ethanes is reported. The use of pyridine as an alternative to phenanthroline, and the ability to carry out the reaction at 60 degrees C or room temperature are the key features of this Cu-Ag mediated cross-coupling methodology. The chemistry is compatible with (hetero)aryl halides, offering a platform to develop products of interest in material and medicinal chemistry.
