Aromatic and aliphatic aldehydes are transformed in 1,1-diacetates (acylals) in mild conditions, by a treatment with acetic anhydride and a Wells-Dawson acid (H 6 P 2 W 18 O 62 •24H 2 O). gem-Diacetylation proceeds in Ac 2 O with a little as 1% mol Wells-Dawson acid at room temperature and under sol
