Ultrasound-Assisted Synthesis of Acylals Catalyzed by Stannum (IV) Phosphomolybdate under Solvent-Free Condition

摘要

An efficient method for the synthesis of acylals from different aldehydes and acetic anhydride in the presence of Keggin-type stannum (IV) phosphomolybdate under ultrasound irradiation at room temperature was achieved. This method provides a new and efficient protocol in terms of cost effective of catalyst, a wide scope of substrates, and simple work-up procedure.
