New alkali salts based on (fluorosulfonyl)(pentafluoroethanesulfonyl)imide [(FSO2)(C2F5SO2)N]−, FPFSI−} anion are introduced, together with a new effective preparation of C2F5SO2NH2 and H[FPFSI]. The former amide was prepared by amination of lithium pentafluoroethanesulfinate (C2F5SO2Li) with NH2OSO3H, which was converted to the H[FPFSI] by sequential chlorosulfonation with SOCl2/ClSO3H, and fluorination by SbF3.
介绍了基于(氟磺酰基)(五氟乙磺酰基)亚胺[(FSO2)(C2F5SO2)N]-,FPFSI-}阴离子的新型碱盐,以及 C2F5SO2NH2 和 H[FPFSI] 的新型有效制备方法。前一种酰胺是通过五氟乙烷亚磺酸锂(C2F5SO2Li)与 NH2OSO3H 的胺化反应制备的,后者通过 SOCl2/ClSO3H 的氯磺化反应和 SbF3 的氟化反应转化为 H[FPFSI]。
