Abstract
Nucleophilic substitution reactions on halobenzenes or triflyl substituted benzenes are carried out in the presence of catalysts. In particular the present invention provides a process leading to optionally substituted hydroxybenzoic, alkanoyloxybenzoic, formyloxybenzoic and alkoxybenzoic acids and optionally substituted hydroxybenzonitriles and alkoxybenzonitriles from substituted 2,6-dihalobenzenes, 2-halo-6-triflylbenzene and 2,6-ditriflylbenzenes.
