Application

Gold Catalysts — 21st Century ′Gold Rush′
Silver trifluoromethanesulfonate is a reactive triflating agent and source of soluble silver ions useful for formation of electrophilic onium species, and promotion of Friedel-Crafts, nucleophile alkene cyclization, and esterification reactions.
It can also be used:
  • To obtain olefins from secondary phosphates and thiophosphates.
  • As a reagent in the etherification of alcohols with primary alkyl halides under mild conditions.
  • To generate cationic rhodium catalysts from chlororhodium complexes for the hydrophosphination of acetylenes.
  • As a catalyst for the preparation of silyl ethers by hydrosilylation of aldehydes.
