Abstract Poly(4-vinylpyridinium) perchlorate has been used as a supported, recyclable, environmentally-benign catalyst for the formation of acylals from aliphatic and aromatic aldehydes in good to excellent yields under solvent-free conditions. Notably, the reaction conditions were tolerant of ketones. This methodology offers several distinct advantages, including its operational simplicity and high
摘要 聚(4-乙烯基吡啶)高氯酸盐已被用作负载型、可回收、环境友好的催化剂,用于在无溶剂条件下以良好至极好的收率从脂肪族和芳香族醛形成酰基。值得注意的是,反应条件对酮是耐受的。这种方法提供了几个明显的优势,包括操作简单和产品收率高,以及在避免使用有毒催化剂和溶剂方面是绿色的。此外,催化剂可以回收和重复使用多次而不会损失其活性。
