标题 :Process for the halogenation, nitration and fluorination of aromatic derivatives
发明人：DESBOIS MICHAEL; DISDIER CAMILLE
权利人:RHONE POULENC SPEC CHIM
摘要:A process for the halogenation (bromination or chlorination)/nitration/fluorination of aromatic derivatives substituted by at least one group containing a halogenoalkyl unit. The aromatic derivative is reacted with a halogen and a nitrating agent in liquid hydrofluoric acid. The products obtained are useful as intermediates for the synthesis of compounds having a plant-protecting or pharmaceutical activity.

标 题:Process for preparing fluorinated aromatics

摘要:It is known to prepare fluorinated aromatic compounds of the formula I in which X, Y and Z can have the meaning specified in the description, by reacting aromatic compounds of the formula II in which X, Y and Z have the meaning specified for formula I, with fluorine in a reaction medium. According to the invention, the direct fluorination is carried out in a reaction medium containing polyfluoroalkanesulfonic acids of the formula IIICFnH3-n(CFY)m-SO3H(III)in which m, n and Y have the meaning specified in the description. By this means, it is possible, particularly advantageously to provide a process, which improves the known processes not only with regard to the selectivity and the yield, but also with respect to the quality of the resulting products of the process in a manner not readily predictable. Fluorinated aromatic compounds of the formula I as intermediates for active compound synthesis.
