Modification of Ru/SiO with metal oxides (MoO, WO, and ReO) improved the activity and selectivity in the hydrogenation of 3-nitrostyrene to 3-aminostyrene under mild conditions such as 0.3 MPa H, 303 K, and no solvent. Ru-MoO/SiO(Mo/Ru = 1/2) catalyst was applicable to various substituted nitroarenes, providing the corresponding substituted aminoarenes in high yields (85-99%).
