WebOct 21, 2014 · An air- and moisture-stable fluoroiodane in the presence of AgBF 4 is suitable for selective geminal difluorination of styrenes under mild reaction conditions. One of the C F bonds is formed by transfer of electrophilic fluorine from the hypervalent iodine reagent, while the other one arises from the tetrafluoroborate counterion of silver. Deuterium … WebSilver hexafluorophosphate is a commonly encountered reagent in inorganic and organometallic chemistry. It is commonly used to replace halide ligands with the weakly coordinating hexafluorophosphate anion; the abstraction of the halide is driven by the precipitation of the appropriate silver halide. Illustrative is the preparation of ...
