A metal‐free, room temperature protocol for the regioselective chloroazidation of internal alkynes is disclosed. The reactions of internal alkynes with trimethylsilyl azide (TMSN3) in the presence of 1,3‐dichloro‐5,5‐dimethylhydantoin (DCDMH) afforded the corresponding chloroazidoalkenes in good yields. This reaction has good functional group tolerance and is operationally simple.
公开了用于内部炔的区域选择性氯叠氮化的无金属室温方案。在1,3-二氯-5,5-二甲基乙内酰脲(DCDMH)存在下,内部炔烃与三甲基叠氮化硅(TMSN 3)的反应得到了相应的氯叠氮基烯烃,收率很高。该反应具有良好的官能团耐受性,并且操作简单。
