AROMATIC SULPHONYLIMIDES, PREPARATION THEREOF AND USE THEREOF AS ELECTROLYTE
-
Page/Page column 12, (2010/07/10)
The invention relates to a process for preparing aromatic sulphonylimides, to the sulphonylimides obtained, and to the use thereof as salt of an electrolyte. The sulphonylimides correspond to the formula [R—SO2—N—SO2R′]rM (I). R′ is an ArZL- group. R′ is a perfluoroalkyl group or an ArZL- group. Z is an S, SO or SO2 group. L is a —(CF2)n—CFRf— group. n is 0 or 1; Rf represents F or a C1 to C8 perfluoroalkyl group; Ar is an aromatic group. M represents H, an alkali metal cation, an alkaline earth metal cation, a trivalent or tetravalent metal cation, or an organic cation. The process consists in preparing a compound RSO2N(R′)SO2R′ from RSO2F, and in replacing the group R′ by nucleophilic substitution reaction so as to obtain the compound (I), R′ being a benzyl or trimethylsilyl group.

(Chemical Equation Presented) An efficient preparation of new fluorinated lithium and ammonium sulfonimides, from the corresponding sulfonyl fluorides, is reported. These sulfonyl fluorides are reacted with benzylamine, then triflated. Due to the high lea
