Procedure

89.5 g (0.875 mol, 7 eq) of manganese dioxide are added to a solution of 38.30 g (0.125 mol, 1 eq) of (3-butoxy-4-iodophenyl)methanol in 250 mL of dichloromethane. The reaction medium is stirred at room temperature for 18 hours and then filtered through silica gel. The solvent is evaporated off to give 29.61 g of 3-butoxy-4-iodobenzaldehyde in the form of an orange-colored oil. Yield=78%.
