Versuchsvorschrift

To a solution of 3-methyl-2-nitrobenzyl alcohol (16.7 g, 100 mmol) in 300 mL of benzene was added activated manganese (IV) oxide (43.5 g, 500 mmol). The resulting mixture was stirred at 80° C. for 24 h. The reaction mixture was allowed to cool and then was filtered through a pad of Celite and concentrated in vacuo to afford 16.2 g of 3-methyl-2-nitrobenzaldehyde, which was pure enough to be used without purification.
