In this work the preparation of orthophenylenediamine (OPDA) from 4-chloro-2-nitroaniline was studied on alumine supported palladium catalysts. High OPDA yields were obtained on catalysts containing stabilized ionic palladium. In the preparation of the given palladium containing catalysts anchoring type surface reactions were used. The existence of palladium in ionic form was evidenced by XPS and EPR measurements.
