Catalysts for nucleophilic substitution, synthesis thereof, composition containing them and use thereof

摘要

The invention concerns novel catalysts for aromatic nucleophilic substitution. Said catalysts are compounds of the general formula (I), wherein: R₁, R₂, R₃, R⁴, R₅, and R⁶, identical or different, are selected among hydrocarbon radicals; the Pn's, advantageously the same, are selected among metalloid elements of column V of a period higher than nitrogen; Z is a metalloid element of column V, advantageously distinct from Pn; preferably a nitrogen (N, P, As, Sb). The invention is applicable to organic synthesis.
