実験手順

Silver trifluoromethanesulfonate was prepared by slowly adding silver carbonate (13.42 g, 0.052 mol) and small amounts of water (total amount of water was 30 ml) to 14.60 grams (0.097 mol) trifluoromethanesulfonic acid dissolved in 100 ml of 1,1,2-trichloro-1,2,2-trifluoroethane contained in a flask. The solution was filtered to remove residual solids, and the two-phase filtrate was separated into organic and aqueous phases. The aqueous phase was evaporated to dryness to give 15.46 grams of silver salt. The salt was dissolved in 50 ml water; the solution was filtered; and the filtrate was evaporated to dryness. The residual silver trifluoromethanesulfonate was dried at 140° C. in a vacuum oven for four hours. The silver trifluoromethanesulfonate melted at 336°- 338° C. and gave the following elemental analysis: % Ag, 44.24; % C, 4.79; % S, 12.5. Infrared spectral analysis showed major absorption peaks at 8.1, 8.6, 9.8 and 13.05 μ, which are consistent with the indicated structure.
