METHOD FOR CONDENSING ONE OR MORE CARBONYL COMPOUNDS ON CARBOCYLIC AROMATIC THIOETHERS OR ETHERS IN AN ACID MEDIUM

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.
