摘要

他们首先发现，在二甲基亚砜（DMSO）中，烷基溴可以作为催化剂，将氯原子从烷基氯转移到羰基化合物的 α 碳上。机理研究进一步证实了这一点，研究小组据此提出了一系列事件：卤化化合物与二甲基亚砜在高温下反应生成烷氧基锍盐，锍盐水解为相应的醇和卤化氢。然后，酸性条件和二甲基亚砜将溴离子氧化成 Br+，Br+受到烯醇的侵蚀，生成溴化酮，最终在卤素交换反应中与游离氯反应，溴离子再生，生成α-氯化酮。事实上，有几种烷基溴可以作为催化剂，特别是伯或仲烷基，如溴化异丙基，而氯化苄则是一种很好的氯转移试剂。研究小组还发现，在这些条件下，具有低立体阻碍的酮很容易发生反应，生成α-氯酮。由于酮在氯化前会异构化成烯醇，研究人员利用这一点，在氢溴酸和自由基聚合抑制剂的催化下，使用氯化苄对芳基共轭烯烃进行氯羟化。
