Abstract:
Summary Nitroarenes can be reduced in high yields to the corresponding anilines by transfer hydrogenation using a stable H-donor,
polymer-supported formate (PSF) in combination with palladium acetate (catalytic). The reactions occur at 100–120∘C in dimethyl-formamide and the PSF can be recycled for at least three runs. The procedure is chemoselective for nitro group;
ester, ketone, aldehyde, and halide substituents on aromatic ring remain unaffected.
