Application
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:
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.

A novel rhodium-catalyzed hydrophosphination of alkynes using a silylphosphine as a phosphino group source is described. A variety of alkynes, both terminal and internal ones with aryl, alkyl, and carboxyl groups, gave the corresponding alkenylphosphines in a highly regioselective and
