| | 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.] |
