| Use | Reagents for halogenation with trifluoromethanesulfonic acid; glycosylation reagent of halogenated glycosyl; deprotection with thiol as protective group Reagents; The reaction of producing olefins with hypophosphate and thiophosphate; Reagents for etherification of halogenated hydrocarbons and alcohols under mild reaction conditions; Used to generate ion catalyst from rhodium chloride complex rhodium; applied to the acetylene of hydrogenated phosphorous acid; a catalyst for the preparation of silyl ether by the hydrosilylation of aldehydes |
| production method | should react in the dark. In a 500ml bottle, 300ml of water is filled, 60g(0.4mol) of trifluoromethanesulfonic acid is slowly added, and the bottle is filled with a magnetic stirrer coated with polytetrafluoroethylene. Put the bottle in an ice bath to cool. 48.5g(0.21mol) of powdered silver oxide was added in installments. Remove the cold bath, continue stirring in the dark for 25min, and filter out the suspended matter from the porous glass sand core funnel. The filter residue is washed with 100ml distilled water, and the residue is dissolved in 250ml of acetone. The acetone solution was filtered through a porous glass sand core funnel. The solvent was evaporated, the product was ground into fine powder, and dried at 100 ℃ for 6 hours at 3.32Pa to obtain 87.9g(98%) of silver trifluoromethanesulfonate. The product should be stored in a dryer to avoid light. Silver trifluoromethanesulfonate can also be made from the reaction of barium trifluoromethanesulfonate with silver carbonate. |
