标题:Method for the synthesis of sulfonyl imides
摘要:Method for the synthesis of sulfonylimidides having the formula M((RSO2)2N)y, whrein 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 C1 to C12, and y is the valence of M. On the one hand, a silazane component selected amongst the silazane compounds M(((R2)3Si)2N)y or the associations of a silazane derivative A((R2)3Si)2N or a fluoride M1Fz of low cross-linking energy is reacted with, on the other hand, at least one sulfonic halogenite component consisting of a sulfonyl fluoride RSO2F or in the association of a sulfonyl chloride RSO2Cl with a fluoride M1Fz, M, R and y having the above-mentionned significations, M1 being selected amongst the Ms and being optionally identical to M, z being the valence of M1 and R2 representing an alkyl in C1 to C4. The imidides obtained for which the R2 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.

发明人：ROQUES NICOLAS
权利人:RHODIA CHIMIE SA
摘要:This invention provides compounds of formula: n n n in which R f is a radical that carries a perfluoromethylene group, which group ensures bonding to the remainder of the molecule; R1 and R3, which can be the same or different, are chosen from among hydrogen and alkyl or aryl radicals; Ψ is an electroattractor group such that Ψ-O—H is an acid whose pKa (in water) is at most equal to 8, advantageously 6, and preferably 5. These compounds are useful for the synthesis of nitrogen-containing heterocyclic compounds.
