Abstract
The present invention relates to a process for the acylation or sulphonylation of an aromatic compound.More particularly, the invention relates to a process for the acylation or sulphonylation of an activated or deactivated aromatic compound.The invention is applied to the preparation of aromatic ketones or sulphones.The process for the acylation or sulphonylation of an aromatic compound which consists in reacting at least one aromatic compound with an acylating or sulphonylating agent, in the presence of a Friedel-Crafts catalyst is characterized in that the acylation or sulphonylation reaction is carried out in liquid phase under microwave irradiation.
