  • Reductive Chlorination and Bromination of Ketones via Trityl Hydrazones
    作者:Julius R. Reyes、Viresh H. Rawal
    DOI:10.1002/anie.201510909
    日期:2016.2.24
    A method is presented for the direct transformation of a ketone to the corresponding reduced alkyl chloride or bromide. The process involves the reaction of a ketone trityl hydrazone with tBuOCl to give a diazene which readily collapses to the α‐chlorocarbinyl radical, reduction of which by a hydrogen atom source gives the alkyl chloride product. The use of N‐bromosuccinimide provides the corresponding
    提出了一种将酮直接转化为相应的还原烷基氯或溴的方法。该方法涉及酮三苯甲基腙与t BuOCl 反应生成二氮烯,该二氮烯很容易坍缩为 α-氯代羰基自由基,氢原子源将其还原得到烷基氯产物。N-溴代琥珀酰亚胺的使用提供了相应的烷基溴。这种独特的转变提供了一种还原性卤化,补充了 Barton 的氧化还原中性卤乙烯合成。
