Efficient reducing system based on iron for conversion of nitroarenes to anilines
Reduction of nitroarenes with low solubility in EtOH-H2O to anilines easily occurs in a Fe-NH4Cl-acetone-H2O system, and treatment of the same nitroarenes with Fe-NH4Cl-EtOH-H2O hardly furnished the corresponding products. Under the reaction condition, the reducible or hydrolysable groups are not affected.
