Abstract

Modification of Ru/SiO₂ with metal oxides (MoO_x, WO_x, and ReO_x) improved the activity and selectivity in the hydrogenation of 3-nitrostyrene to 3-aminostyrene under mild conditions such as 0.3 MPa H₂, 303 K, and no solvent. Ru–MoO_x/SiO₂(Mo/Ru = 1/2) catalyst was applicable to various substituted nitroarenes, providing the corresponding substituted aminoarenes in high yields (85–99%).
