We describe here the first example in which glycerol has been transformed into chlorohydrin esters using an ionic liquid and hydrated aluminium chloride. The method avoids using Crown-18 ether, which was needed to obtain a similar yield when KCl was used. Alkyl and aryl acids can be used, although yields are very dependent on the carboxylic acid used.
我们在这里描述第一个例子,其中使用离子液体和水合氯化铝将甘油转化为氯醇酯。该方法避免了使用Crown-18醚,而使用KCl时需要使用Crown-18醚才能获得相似的收率。可以使用烷基和芳基酸,尽管产率非常取决于所用的羧酸。
