benzylation of 1,3-dicarbonyl compounds. β-Keto enol ethers were obtained when cyclic 1,3-dicarbonyl compounds used in this conditions instead of linear ones. The present methodology offers a practical, simple, mild, environmentally friendly, and time-saving method for etherification. Very low loading of catalyst, ease of workup, ease of handling, and reusability of catalyst are other advantages of
摘要K5CoW12O40被用作1,3-二羰基化合物苄基化的高效催化剂。当在这种条件下使用环状1,3-二羰基化合物代替线性化合物时,可获得β-酮烯醇醚。本方法提供了一种实用,简单,温和,环保且省时的醚化方法。催化剂的极低负载,易于后处理,易于处理以及催化剂的可重复使用性是该催化剂的其他优点。
