Abstract (en)

[origin: FR2760744A1] The invention concerns a method for the acylation or sulphonation of an aromatic compound. More particularly, the invention concerns a method for the acylation or sulphonation of an activated or deactivated aromatic compound and is useful for preparing aromatic ketones or sulphones. The method consists in reacting at least an aromatic compound with an acylation or sulphonation agent, in the presence of a Friedel-Crafts catalyst and is characterised in that the acylation or sulphonation reaction is carried out in liquid phase under microwave radiation.
