Abstract
The invention concerns a method for the condensation of aromatic derivative(s) or a sulphinic derivative by a perhalogenated, advantageously perfluorinated, carbon atom. Said method is characterized in that it consists in subjecting said sulphinic derivative and said aromatic derivative to the action of a strong acid whereof the pKa is not more that 0. The invention is applicable to organic synthesis.
Claims11
A process for the condensation of an aromatic compound and of a sulfinic compound, the carbonaceous chain of which is attached to the sulfinic functional group via a perhalogenated carbon atom, comprising the steps of:
- a) carrying out a condensation reaction in a reaction mixture comprising said sulfinic compound, said aromatic compound and a strong acid which is an hydrohalic acid, a sulfonic acid, a perhalosulfonic acid, a flurosulfinic acid and sulfuric acid, and
- b) recovering the product obtained in step a).
