Iron-catalyzed direct reduction of allylic halides with benzylic alcohol was achieved, providing a new, simple, and efficient method for conducting highly regioselective hydrodehalogenation. This method not only features a readily available reductant, an inexpensive catalyst, simple manipulation, and good tolerance of functional groups including nitriles, nitro, esters, and methoxyl groups, it also
实现了铁催化的苄醇对烯丙基卤的直接还原,为进行高区域选择性加氢脱卤提供了一种新的,简单而有效的方法。该方法不仅具有易于获得的还原剂,廉价的催化剂,简单的操作以及对腈,硝基,酯和甲氧基等官能团的良好耐受性,而且反应条件温和并且具有完全的区域选择性,因为只有卤化物位于盟友位置减少。或者,该方法可以用于将苄醇选择性转化为芳族醛而不会过度氧化为羧酸。
