In the initial stages of the electrooxidation of alken-1-ylarenes-propenyl-benzene (Ia) and 4-propenylanisole (Ib) - in aqueous alcohol solutions, 1,2-dialkoxypropyl- (II), 1-hydroxy-2-alkoxypropyl- (VII), and 1,2-dihydroxy-propyl arenes (VIII) are formed.Subsequent rupture of the C-C benzyl bond converts the ethers (II) into benzaldehyde acetals (III) and benzaldehydes (IV), and compounds (VII) and (VIII) into (IV).Benzaldehydes (IV) are also formed from (II) by hydrolysis of the acetals (III) - partly for (IIIa) and completely for (IIIb).Electrolysis of (Ia and Ib) in aqueeous alcohol solution leads mainly to their conversion into benzaldehydes (IV).
