4-Methylanisole → 4-Methoxybenzaldehyde

Participants

Reaction Steps

A methanol solution of 24.6 g of cerium(III) nitrate is placed into an anode chamber, and a methanol solution of 2 g of ammonium nitrate is placed into a cathode chamber. The cerium salt is electrolyzed with a constant current of 50 mA to pass electricity across the electrodes in a quantity of 1.2 F/mole. A 1.22 g quantity of p-methyl anisole is added to the solution withdrawn from the anode chamber after the electrolysis, and the mixture is stirred for 30 minutes. The same procedure as in Example 1 is thereafter repeated, giving 1.312 g of anisaldehyde. Yield: 96.5%.
