Abstract:
Process for preparing a compound corresponding to the formula in which:Mm+ is a proton or a metal cation having the valency m, chosen from ions of alkali metals, of alkaline-earth metals, of transition metals or of rare-earth metals, or an organic onium cation or an organometallic cation, 1&lE;m&lE;3; Q represents N, CR5, CCN or CSO2R5; X1 and X2 represent, independently of each other, S&boxH;Z3, S&boxH;Z4, Pâ€”R3 or Pâ€”R4; Z1, Z2, Z3 and Z4, denoted below by Zi, represent, independently of each other, O, NCâ‰¡N, C(Câ‰¡N)2, NS(&boxH;Z)2R6 or C[S(&boxH;Z)2R6]2, Z having the same meaning as Zi, with the proviso that, in a segment â€”X1â€”Qâ€”X2â€”, not more than 3 groups Zi represent O; R1, R2, R3, R4, R5 and R6 represent, independently of each other, Y, YOâ€”, YSâ€”, Y2Nâ€” or F; Y represents a monovalent organic radical chosen from alkyl, alkenyl, oxaalkyl, oxaalkenyl, azaalkyl, azaalkenyl, aryl, alkylaryl or perfluoroalkyl radicals, or from the radicals obtained from the abovementioned radicals by substitution, in the chains and/or the aromatic part, with hetero atoms chosen from halogens, oxygen, nitrogen, sulfur or phosphorus; with the proviso that if said heteroatom is sulfur or phosphorus, said sulfur or phosphorus atom can optionally be in the form of a â€”SOâ€” group, a â€”SO2 group or a >POâ€” group, or alternatively Y is a repeating unit of a polymeric backbone, wherein the process comprises reacting a compound R1â€”X1(Z1)â€”Qâ€”X2(L)R2 with a compound A2Z2, in which: A is an alkali metal, a proton, an amino or phosphorus-containing base, a trialkylsilyl group, a dialkylstannyl group, LiH, MgCl, Li, MgLl, ZnL1, CdLl, Cu, Mg, Zn, Cd, Hg or a trialkylsilyl, trialkylgermanyl or trialkylstannyl group, L and L1 are leaving groups.
