The hydrogenation of the aromatic rings in dibenzo-18-crown-6 is accompanied by hydrogenolysis of the carbon-oxygen bonds of the polyether ring.The selectivity of hydrogenation depends on composition of the solvent, the nature of the catalyst, the temperature, the hydrogen pressure, and other factors.Rhodium and ruthenium catalysts exhibit the highest activity in the reaction: in water, Ru > Rh > Pt, Pd; in 2-propanol, Rh >> Ru > Pt > Pd.The hydrogenation and hydrogenolysis are concurrent reactions, and the former is favored by high pressure.
