| 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.
