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.

摘要:Nitroarylacetic acid esters are prepared by reacting a nitroaromatic compound which is devoid of halogen on the aromatic ring carrying a nitro group with an alpha,alpha-disubstituted acetic acid ester in an inert solvent and in the presence of a base so that the ester undergoes a nucleophilic substitution on an unsubstituted ring carbon of the nitroaromatic compound during which an alpha-substituent functions as a leaving group. Nitrobenzene acetic acids and their esters are useful intermediates for the synthesis of pharmaceuticals.
