Description
Summary:An efficient chemoselective reduction of aromatic nitro compounds to corresponding amino analogs was achieved using palladium doped TiO 2 (Ti 0.97 Pd 0.03 O 1.97 ) nanoparticles. The reductions are effectively carried out in the presence of aromatic nitro compounds of various other reducible functional groups such as halo, alkoxy, carbonyl, and cyanide. The reduction of aromatic nitro compounds to aromatic amines was recognized with excellent yield (100%) by using nano porous palladium as a sustainable catalyst and as a hydrogen source. Reduced amines were well characterized using PXRD, 1 H NMR, and 13 C NMR, spectroscopy. The stability and efficiency of the catalyst for reduction of 4-Nitrophenol were repeated for 9 cycles and the recovered catalyst was analyzed by XRD.
