冰乙酸—乙酸酐—高氯酸体系通常用作醇的快速乙酰化,也曾用于醇的脱水反应,但我们发现三级醇类化合物在上述体系中可以形成双键的乙酰化产物,收率颇高,因此,我们做了一些探索。
The acetic acid-acetic anhydride-perchloric acid system is commonly used for the rapid acetylation of alcohols and has also been used for the dehydration reaction of alcohols. However, we found that tertiary alcohol compounds can form double bond acetylation products in the above system. Rate is high, so we did some exploration.
