The reduction can also be carried out using Fe/acetic acid. A mixture of 0.784 g of iron, 1.62 mL of glacial acetic acid, 0.544 g of sodium acetate, and 1 g of 2-(5-chloro-2-nitrophenyl)cyclo-hexanone was refluxed in 80 mL of 4:1 (v/v) ethanol/water for 2 hr. The mixture was cooled, ethanol was evaporated, and the residue was extracted into methylene chloride. Work-up followed by column chromatography on silica yielded 0.160 g (20%) of the named product.
