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.
