Yield:87-60-5 99.2%

Reaction Conditions:

with hydrazine hydrate monohydrate in ethanol; for 0.333333 h;Reflux;

Steps:

2.4 Catalytic reduction of nitroarenes over Fe3O4(at)GO composite

General procedure: A mixture of an aromatic nitro compound (e.g., nitrobenzene, 2.4600 g, 20 mmol), ethanol (12 mL) and as-prepared Fe3O4(at)GO composite (0.0773 g, 3.1 wt% of nitrobenzene) was heated to reflux with stirring, followed by dropwise addition of hydrazine hydrate (72 mmol, 3.6 equiv.). The reaction mixture was kept at reflux with stirring and the reaction progress was monitored by gas chromatography. The Fe3O4(at)GO composite was separated by applying an external magnetic field at the end of the reaction and washed with ethanol three times before being vacuum dried. Then, the composite was weighed and recycled for the reduction reaction. Quantitative and qualitative analyses of the reactions were performed using GC and GC-MS, and the products were identified by comparison with authentic samples.
