The reduction of nitroarenes is an important process as the products, aromatic amines, are
versatile intermediates and precursors in the preparation of dyes, pharmaceuticals, pigments,
agrochemicals and polymers [1,2]. A variety of procedures and reducing agents are available
for this purpose [3]. The main limitations of these works were prolonged reaction time, low
yields, harsh conditions, use of harmful organic solvents, tedious work‐up procedures and the
use of expensive catalysts.In this work, we have used the nanomagnetic core-shell
Fe3O4@Cu(OH)x as a heterogeneous catalyst for reduction of nitroarenes to arylamines in
water (Figure 1). Remarkable reusability and easy separation of the nanocatalyst, high yields
and mild reaction conditions as well as the benefits of using water as a green solvent are the
advantages which make this protocol a perfect candidate for the reduction of nitroarens.
