Abstract: In this study, we developed a metal-free and highly chemoselective method for the reduction of aromatic nitro compounds. This reduction was performed using tetrahydroxydiboron [B2(OH)4] as the reductant and 4,4'-bipyridine as the organocatalyst and could be completed within 5 min at room temperature. Under optimal conditions, nitroarenes with sensitive functional groups, such as vinyl, ethynyl, carbonyl, and halogen, were converted into the corresponding anilines with excellent selectivity while avoiding the undesirable reduction of the sensitive functional groups.

YieldReaction ConditionsOperation in experiment
With tetrakis(triphenylphosphine) palladium(0); at 110℃; for 8h; Step B: 4-Formyl-2-methoxybenzonitrile: A mixture of the sulfonate (37.0 g, 130 mmol), zinc cyanide (61.1 g, 521 mmol) and tetrakis triphenyiphosphine palladium (0) (22.57 g, 19.53 mmol) in DMF (300 mL) were stirred at 110 C for 8 hr. EtOAc was added to the reaction mixture and the organic layer was washed two times with water, dried, filtered and concentrated. The crude product was then purified by column chromatography (silica gel, ethylacetate/hexanes 3:7) whichafforded the title compound: LC/MS: (IE, m/z) [M + 1] = 162.34.
