Chemical properties
light beige crystalline powder
The Uses of SILVER TRIFLUOROMETHANESULFONATE
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.
General Description
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.
Purification Methods
Recrystallise it twice from hot CCl4 [Alo et al. J Chem Soc, Perkin Trans 1 805 1986]. Store it in the dark. [Beilstein 3 IV 34.]
