    • The invention provides a new family of compounds and a method of making the compounds. The new compounds are useful as ion conductive salts, and particularly useful as salts for batteries. The compounds of the invention are prepared from three principal reagents, bis (trifluoromethanesufonyl) methane (CF.sub.3 SO.sub.2).sub.2 CH.sub.2 ; benzoyl chloride; and pyridine which facilitates reaction and then is removed. A precursor sodium salt (CF.sub.3 SO.sub.2).sub.2 CHNa is first prepared. Then, equimolar amounts of the precursor sodium salt and pyridine are dissolved in anhydrous acetonitrile. A stoichiometric amount of the selected substitute benzoyl chloride is then added drop by drop. After addition of Li.sub.3 PO.sub.4, there is pyridine release and formation of the product of the aforesaid two reagents. In the benzene ring, R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R.sub.5 are each identical or different and are each independently selected from hydrogen and an electron withdrawing substituent.
    • 本发明提供一种新的化合物族和一种制备该化合物的方法。 新化合物可用作离子导电盐,并且特别用作电池的盐。 本发明的化合物由三种主要试剂,二(三氟甲磺酰基)甲烷(CF 3 SO 2)2 CH 2; 苯甲酰氯; 和吡啶,这有助于反应然后被除去。 首先制备前体钠盐(CF 3 SO 2)2 CHNa。 然后将等摩尔量的前体钠盐和吡啶溶于无水乙腈中。 然后逐滴加入化学计量的所选择的替代苯甲酰氯。 添加Li3PO4后,存在吡啶释放并形成上述两种试剂的产物。 在苯环中,R 1,R 2,R 3,R 4和R 5各自相同或不同,各自独立地选自氢和吸电子取代基。
