They have synthesized new, active, and highly selective metal complex catalysts derived from palladium salts immobilized on silica gel modified by Schiff bases of heterocyclic aldehydes. The rate of the dechlorination of chloronitrobenzenes using these catalysts is 3-40 mole/min g-at Pd and the yield of nitrobenzene is virtually quantitative. The best results were obtained by using palladium complexes with silica gel modified by pyridyl-4-, thienyl-2-, and pyrryl-2-aldiminopropyl groups. The initial rate for the conversion of chloronitrobenzene on these catalysts is 38, 29, and 21 mole/min x g-at Pd.
