Synthesis of Acylals from Aromatic Aldehydes and Their Deprotections Catalyzed by Synthetic Phosphates: Practical and Ecological Approach | Chapter 9 | Current Perspectives on Chemical Sciences Vol. 7

 Effective and clean preparation of aromatic aldehyde acylals in the presence of synthetic phosphates (flourapatite and hydroxyapatite doped with ZnCl2 and ZnBr2) and acetic anhydride was easily achieved under solvent-free conditions at room temperature at high yields (86% - 97%). The deprotection of the resulting acylum was also accomplished by using the same microwave irradiation catalysts. Excellent yields (82 percent - 96 percent) and a quick reaction time are consistently advantaged by this strategy (3 - 4 min).
