Abstract
The synthesis of acylals (1,1-diacetates) via the reactions of aldehydes with acetic anhydride was carried out in 85-97% yields at room temperature under ultrasound irradiation catalyzed by the Brønsted acidic ionic liquid [bmpy]HSO(4). This method provides several advantages, such as solvent-free conditions, operational simplicity, higher yields, and reduced environmental consequences. The ionic liquid was recovered and reused.
摘要
通过超声辐射在 Brønsted 酸性离子液体 [bmpy]HSO(4)催化下，室温条件下，醛与乙酸酐反应合成了酰基化合物（1,1-二乙酸酯），产率为 85-97%。该方法具有无溶剂条件、操作简单、产率高、环境影响小等优点。离子液体可回收并重复使用。
