white to pale yellow crystalline powder
Silver Hexafluoroantimonate(V) is used as a catalyst in the synthesis of isocoumarins through benzothiadiazine-fused.
Silver hexafluoroantimonate is useful as a metathesis reagent with organic and organometallic halides; a mild Lewis acid catalyst for the rearrangement of α-haloketones, pinacols, epoxides, and propargyl esters.
Silver hexafluoroantimonate has been made from SbF3 (or Sb2O3), AgCl, and Bromine Trifluoride, but is more readily prepared by reacting Antimony(V) Fluoride and Silver(I) Fluoride in anhydrous HF at -78 to 0 °C, washing with pet ether, and drying in vacuo.
