monomer halogen, the need for in situ generation of unstable halogen azides (XN3), applicability to one type of haloazidation and inability to precisely control selectivity. Herein, we developed a universal strategy for haloazidation of alkenes through controlling the reactivity of IBA-N3 by switching halogen salts, allowing for the synthesis of a diversity of halogen azide products.

虽然卤代叠氮化反应的路线有多种,但仍存在不可避免的问题,如单体卤素对环境不友好、需要原位生成不稳定的卤代叠氮化物(XN 3 )、仅适用于一种类型的卤代叠氮化反应以及无法实现卤代叠氮化反应等。精确控制选择性。在此,我们开发了一种通用的烯烃卤代叠氮化策略,通过切换卤素盐来控制 IBA-N 3 的反应性,从而合成多种卤素叠氮化物产品。机理研究表明,通过切换卤盐来调节IBA-N 3 的反应活性,可以可控地产生不同的中间体,从而实现烯烃卤叠氮化反应的区域选择性和化学选择性。
