摘要:The invention concerns a halogenation in position meta of a phenol fuction. Said halogenation comprises a step which consists in halogenating an aromatic derivative of a medium or advantageously strong acid, the aromatic radical being a phenyl substituted in ortho and in para by functions attracting electrons by inductive effect. The invention is applicable to organic synthesis.
