“…1,2 Traditional approaches such as Béchamp reduction method, generates large amount of waste and requires mineral acids, which is not appropriate for acid sensitive functional groups. 3 In recent years, an increasing attention has been paid to catalytic nitro reduction using transition metals such as Cu, 4,5 Co, 6,7 Pd, [8][9][10][11] Ni, 12,13 Au [14][15][16][17] and Zn 18,19 . Along this line, due to the superior catalytic activity in bimetallic variants relative to their monometallic analogs, variety of bimetallic catalysts have been developed for organic reactions including the reduction of nitroarenes.…”
