Product 1

HCID 312444-MethoxybenzaldehydeYield 94.8%

Procedure

The same procedure as in Example 1 is repeated except that the cerium salt is electrolyzed with 100 ml of 2 to 3% by weight aqueous solution of nitric acid placed into the cathode chamber in place of ammonium nitrate. p-Methyl anisole is oxidized with the solution withdrawn from the anode chamber to give anisaldehyde in a yield of 94.8%.

Workup

  1. customwithdrawn from the anode chamber
