Abstract
Aromatic nitro compounds were chemoselectively reduced to the corresponding amines using recyclable polymer-supported formate as a hydrogen donor in the presence of low-cost magnesium powder at room temperature. Use of the immobilized hydrogen donor affords the product amine in excellent yield (90–97%) without the need for any chromatographic purification steps. This method was found to be highly facile with selectivity over several other functional groups, such as halogen, alkene, nitrile, carbonyl, ester, amide, methoxy, phenol, and hydroxyl groups.
