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:
  • 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

A novel method has been devised for the synthesis of 2,4,5-trisubstituted pyrrole derivatives through the coupling of α-diazoketones with β-enaminoketones and esters using 10 mol % of Cu(OTf)(2). A wide range of 2,3-disubstituted indole derivatives were also prepared from α-diazoketones
