PROCEDE POUR LA CONDENSATION, EN MILIEU ACIDE, D'UN OU PLUSIEURS COMPOSES CARBONYLES SUR DES ETHERS OU THIOETHERS AROMATIQUES CARBOCYCLIQUES

摘要

The present invention relates to a method for condensing at least one carbonyl compound on an electroattractor radical on a carbocyclic aromatic thioether or ether, characterised in that the electroattractor radical present on said carbonyl compound is a fluoroalkyl radical and in that said condensation is carried out in the presence of an effective quantity of a heterogeneous acid catalyst.
