| 摘要 |
Nucleophilic substitution reactions on halobenzenes are carried out in the presence of catalysts. In particular the present invention provides a process leading to optionally substituted hydroxybenzoic and alkoxybenzoic acids and optionally substituted hydroxybenzonitriles and alkoxybenzonitriles from substituted 2,6-dihalobenzenes. |
