Application

Addition of Pd/C to Pd(OH)2/C improves the efficiency of N- or O-debenzylation.
Effectively catalyzes the direct arylation reactions of aryl iodides and bromides in both intra- and intermolecular processes.
Particularly active for hydrogenolysis of benzyl-nitrogen bonds, and has proven successful even where other palladium-on-carbon catalysts have failed.
