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.

With tetrabutylammomium bromide; potassium acetate; palladium diacetate; In N,N-dimethyl-formamide; at 80℃; for 5h;Inert atmosphere; Sealed tube; | General procedure: To a solution of tetrabutylammonium bromide (1.100 g, 3.33 mmol), potassium acetate (0.586 g, 3.57 mmol), and palladium acetate (0.025 g, 0.11 mmol) in DMF (20 mL) were added substituted iodobenzene (2.21 mmol) and 4-nitrostyrene (2.44 mmol). The reaction mixture was recharged with argon and stirred at 80C for 5 h in a sealed tube. The mixture was extracted with ethyl acetate. The organic layer was washed with saturated aqueous NaCl and concentrated in vacuo. The residue was purified by column chromatography on silica gel (petroleum ether/ethyl acetate, 10:3) to afford the intermediate substituted (E)-1-nitro-4-styrylbenzene. To a solution of stannous chloride (2.087 g, 11.05 mmol) in EtOH (20 mL) was added substituted (E)-1-nitro-4-styrylbenzene (2.21 mmol). The reaction mixture was stirred at reflux temperaturefor 4.0 h. The mixture was extracted with ethyl acetate. The organic layer was washed with saturated aqueous NaCl and concentrated in vacuo. The residue was purified by column chromatography on silica gel (dichloromethane/methanol, 10:0.1) to afford pure product. |
