  Silica Gel-Supported Polyphosphoric Acid (PPA/SiO₂) as an Efficient and Reusable Catalyst for Conversion of Carbonyl Compounds into Oxathioacetals and Dithioacetals

  摘要：

  开发了一种简单高效的方法，通过使用负载在硅胶上的多磷酸（PPA/SiO2）作为酸催化剂，将羰基化合物转化为氧硫酯和二硫酯。PPA/SiO2可以轻松从反应混合物中回收，并且在重复使用时没有催化活性下降。

  A simple and efficient method for the conversion of carbonyl compounds to oxathioacetals and dithioacetals using SA/SiO2 as an acid catalyst has been achieved. SA/SiO2 is easily recovered from the reaction mixture and can be reused at least 15 times without loss of catalytic activity.
