YieldReaction ConditionsOperation in experiment
97% With potassium carbonate; In N,N-dimethyl-formamide; at 100℃; for 2h;Inert atmosphere; Example 3 Dicyanoperfluorotoluenesulfonic acid compound (hereinafter abbreviated as 3FNS-1) was synthesized according to the following reaction formula. [Show Image] Under nitrogen atmosphere, 3.38 g of <strong>[1835-65-0]tetrafluorophthalonitrile</strong>, 1.87 g of potassium carbonate and 50 ml of N,N-dimethylformamide were successively added to 5 g of sodium 1-naphthol-3,6-disulfonate (made by Tokyo Chemical Industry Co., Ltd.) and the reaction system was purged with nitrogen, followed by agitation at 100°C for 2 hours. After 2 hours, 50 ml of DMF was added so as to dissolve a precipitated reaction product therein. Next, filtration was carried out to remove the potassium carbonate. The resulting filtrate was dropped in 200 ml of IPA for re-precipitation. The filtrate obtained by filtration was concentrated to dryness under reduced pressure, to which 50 ml of pure water was added for dissolution, followed by purification through column chromatography using cationic exchange resin Dowex 650C (about 100 ml of H type, distillate solvent: water). The fraction whose pH was at 1 or below was concentrated to dryness to obtain 5.31 g of a white powder (yield: 97percent). Molecular weight: 484.38 LC-MS: 482.96 [M-H]-
