Özet
Addressed herein is a general and facile route for the reduction of aromatic nitro, nitrile, and carbonyl compounds to the corresponding primary amines and alcohols, respectively, under ambient conditions. Our reduction approach comprises the tandem AB dehydrogenation and hydrogenation of unsaturated organic groups catalyzed by reduced graphene oxide supported Co30Pd70 alloy nanoparticles (rGO-Co30Pd70) in water/methanol mixture (v/v = 7/3) at room temperature. Monodisperse Co30Pd70 alloy NPs were synthesized by using an organic solution phase protocol involving the co-reduction of cobalt(II) acetylacetonate and palladium(II) acetylacetonate in oleylamine and borane-tert-butylamine mixture at 100 degrees C. The colloidal Co30Pd70 NPs were assembled on reduced graphene oxide (rGO-Co30Pd70) before their use as catalysts in the tandem reactions. A variety of aromatic nitro, nitriles, and carbonyl compounds were tested by the rGO-Co30Pd70 catalyzed tandem reaction and all the corresponding primary amines or alcohols were obtained by the yields reaching up to 99% within reaction times of 5-15 min.
