ABSTRACT:
A process for sulfonylation of halobenzenes, in which a halobenzene is reacted with a sulfonic acid, a precursor or a derivative thereof in the presence of boron trifluoride in an amount such that the absolute pressure of boron trifluoride within the reaction vessel exceeds 1 bar, and in the presence of hydrofluoric acid as a solvent. The resultant products are useful as intermediates in the synthesis of compounds having a phytosanitary (e.g., herbicidal) or pharmaceutical activity.
