The invention relates to a method for carrying out an SNAr-type nucleophilic substitution on an aromatic substrate, characterized in that an aromatic substrate of general formula (I), wherein A represents an aromatic residue motif, X represents a substituent that can be exchanged by an SNAr reaction, R represents one or several substituents that can at least partially deactivate said aromatic substrate, is subjected to the action of microwaves in an organic medium and in the presence of at least one nucleophilic agent that can be exchanged with said substituent X and at least one cationic phase transfer catalyst.
La présente invention a pour objet un procédé utile pour réaliser une substitution nucléophile de type SNAr sur un substrat aromatique caractérisé en ce que l'on soumet un substrat aromatique de formule générale (I) dans laquelle: A symbolise un reste d'un motif aromatique; X représente un substituant susceptible d'être échangé par une réaction SNAr; R représente un ou plusieurs substituants, capable(s) de désactiver au moins partiellement ledit substrat aromatique à l'action de micro-ondes en milieu organique et en présence d'au moins un agent nucléophile susceptible de s'échanger avec ledit substituant X et d'au moins un catalyseur de transfert de phase cationique.
