Platinum catalysts have a much greater tendency than palladium to reduce aromatic and heteroaromatic rings, and a reduced tendency to bring about hydrogenolysis e.g. of benzyl groups. Other applications of platinum catalysts include: reduction of double bonds; aromatic nitro compounds to amines, and to N-arylhydroxylamines in alcoholic solution, containing 1-2% DMSO; hydrazones to hydrazines; imines to amines; benzonitriles to dibenzylamines in the presence of 0.5 mole water.
