    摘要: The invention relates to processes for aromatic nucleophilic substitution by contacting a substrate of formula (III) Ar-Ξ  (III) where Ar is an aromatic group where the nucleus carrying the group Ξ is electron-poor, either because it contains at least one heteroatom in its ring or because the sum of the Hammett constants, σp, of its substituents, apart from said Ξ, is at least 0.2, and Ξ is a leaving group, with a composition containing at least one ionic compound whose cation is of general formula G: (R10)(R9)N—[C(R8)═C(R6)]ν—C(R5)═N+(R1)(R2)  (G) wherein: ν is an integer from 0 to 4, inclusive; R1, R2, R5, R6 and R8, which are identical or different, are a hydrogen or a hydrocarbon group; and R9 and R10, which are identical or different, are a hydrocarbon group; or one or two of the substituents R1, R2, R5, R8, R9, and R10 are connected to other remaining substituent(s) to form one or two or more rings.
