Silver Trifluoromethanesulfonate is used to generate cationic rhodium catalysts from chlororhodium complexes for the hydrophosphination of acetylenes. It is also employed as a catalyst for the preparation of silyl ethers by hydrosilylation of aldehydes.

Silver trifluoromethanesulfonate p-complexes of monoenes, dienes, trienes, monoynes and diynes have been prepared. It reacts with 2-fluoro- and 3-fluoro-4-alkoxystilbazoles to afford the mesomorphic complexes. Iodine monochloride/AgOTf constitutes an efficient promoter system for the O-glycoside synthesis.
