第二部分,我们发展出一个便利且具有高度位向选择性的方法来制备三取代碘化呋喃,由高炔丙基醇可以顺利的得到2,4,5-三取代碘化呋喃。

The conversion of alcohols to alkyl halides was investigated using acidic ionic liquid X as halogenating agent, acidic catalyst as well as medium. The reactions of primary alcohols gave very satisfactory conversions and selectivities except for the substrates with lower boiling point,such as n-octanol and benzyl alcohol. They obtained the corresponding halides with almost quantitative yields(95%-100%).The secondary alcohols also gave the corresponding halides with excellent conversions, however, the by-products of dehydration were detected.
