SILVER TRIFLUOROMETHANESULFONATE Usage And Synthesis

Reactions

Silver precatalyst for the asymmetric allylation of aldehydes
Silver catalyst for intramolecular additions of alcohols and carboxylic acids to inert olefins
Silver catalyst for the fluorination of boronic acids
Silver catalyst for the fluorination of functionalized aryl stannanes
Silver catalyst for cyclopropenation of internal alkynes with donor/acceptor substituted diazo compounds
Silver catalyst for the reaction of 2-alkynylbenzaldehyde with 2-isocyanoacetate

Chemical Properties

light beige crystalline powder

Uses

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.]
