Use of ionic compounds having a delocalised anionic charge as catalyst components

摘要

New ionic compounds corresponding to the formula (R1X1(=Z1)Q-X2(=Z2)R2)m Mm (I) :- M = a proton or metallic cation of valence m chosen from alkali, alkaline earth, transition, rare earth metals or an organic onium cation or organo-metallic cation ;m is greater or equal to 1 or less than or equal to 3 ; -X1 and X2 (Xi) = S=Z3, S=Z4, P-R3 or PR4 ; -Q = N, CR5, CCN or CSO2R5 ; Z1, Z2, Z3 and Z4 (Zi) = =O. =NC?=N, =C(C?=N)2, =NS(=Z)2R6 or =C[S(=Z)2R6]2 : Z = Zi, conditional that, in a segment -X1-Q-X2, no more than 3 Zi groups are =O ; -R1, R2, R3, R4, R5 and R6 (Ri) = Y, YO-, YS-, Y2N- or F ; -Y = 1 - 16C monovalent alkyl, alkenyl, oxa-alkyl, oxa-alkenyl, aza-alkyl, aza-alkenyl, aryl, or alkylaryl, perfluoroalkyl, or radicals obtained from the above radicals by substitution in the chains and/or aromatic part by heteroatoms such as halogens, O, N, S, P : if S or P are present they may optionally be linked to O or substituted N, or Y is a repetition unit of a polymer. Also claimed, are their method of preparation and uses.
