A clean, practical and environmentally friendly synthesis in a homogeneous system has been developed for α-oxoketene S,S-acetals. A mixture of [Bmim]Cl and water was used as medium. The best economical and practical molar ratio of [Bmim]Cl to substrate was 4 to 1. With various types of 1,3-dicarbonyl compounds as substrate, the corresponding α-oxoketene S,S-acetals have been prepared under mild reaction
已开发出一种清洁、实用且环保的均相系统合成方法,用于 α-oxoketene S,S-缩醛。[Bmim]Cl 和水的混合物用作介质。[Bmim]Cl 与底物的最佳经济实用摩尔比为 4:1。 以各种类型的 1,3-二羰基化合物为底物,在温和的反应条件下制备了相应的 α-氧代烯酮 S,S-缩醛用硅胶柱纯化后的产率为53-74%。[Bmim]Cl/水可以循环多次使用。
