Yield: 78%
Reaction Conditions:
with sodium tetrahydroborate in water at 20; for 5 h;chemoselective reaction;
Steps:
2.3 General Procedure fortheReductionofNitroarenes toAmines withNiNPs/DNA
General procedure: In a typical experiment, 0.5mmol of nitroarene and 0.002g(2mol%) NiNPs/DNA were added to 2mL water and thenstirred for 2-3min for thoroughly mixing. Subsequently,1mmol of NaBH4was added to the reaction mixture undermagnetic stirring at room temperature. The extent of thereaction was monitored by thin layer chromatography.Reproducibility of the results was checked by repeating theruns at least three times and was found to be within acceptablelimits (± 3%). When the reaction was completed, thereaction mixture was diluted with ethyl acetate and the catalystwas recovered by centrifugation. The combined organicfractions were dried over Na2SO4and evaporated underreduced pressure. The crude product was purified by columnchromatography on silica gel with a mixture of ethyl acetateand n-hexane as the eluent, and the ratio of ethyl acetate andn-hexane was depended on the structure of the products.The structure of isolated products was verified by 1H NMR.
