An efficient and practical method has been developed for the facile synthesis of 1,2,4-trioxanes by the condensation of β-hydroperoxy alcohols and carbonyl compounds in the presence of a catalytic amount of silica-supported ferric chloride (FeCl3/SiO2) at room temperature. The method has the benefits of operational simplicity, high yields and potential large-scale application. Moreover, the catalyst
在催化量的二氧化硅负载的三氯化铁(FeCl 3 / SiO 2)存在下,通过β-氢过氧醇和羰基化合物的缩合,可以轻松合成1,2,4-三恶烷,这是一种有效而实用的方法。) 在室温下。该方法具有操作简单,产率高和潜在的大规模应用的优点。而且,该催化剂可以通过简单的过滤容易地回收,并且可以重复使用多达五次,同时几乎保持其催化活性。
