ABSTRACT:
Method for the synthesis of sulfonylimidides having the formula M((RSO.sub.2).sub.2 N).sub.y, wherein M is a metal or an ammonium radical quaternary or not, the Rs, which may be identical or similar are organic monovalent radicals, particularly hydrocarbyles and preferably perfluorohydrocarbyles, in C.sub.1 to C.sub.12, and y is the valence of M. On the one hand, silazane component selected amongst the silazane compounds M(((R.sub.2).sub.3 Si).sub.2 N).sub.y or the associations of a silazane derivative A((R.sub.2).sub.3 Si).sub.2 N or a fluoride M.sub.1 F.sub.z of low cross-linking energy is reacted with, on the other hand, at least one sulfonic halogenite component consisting of a sulfonyl fluoride RSO.sub.2 F or in the association of a sulfonyl chloride RSO.sub.2 Cl with a fluoride M.sub.1 F.sub.z, M, R and y having the above-mentioned significations, M being selected amongst the Ms and being optionally identical to M, z being the valence of M.sub.1 and R.sub.2 representing an alkyl in C.sub.1 to C.sub.4. The imidides obtained for which the R.sub.2 are perfluorated radicals and M is an alkaline metal such as Li are usable in association with polyethers for the production of materials of the ionic conduction type for all solid generators in thin films.
