Although hetero-halogen compounds are versatile synthetic intermediates, their one-step preparation methods are scarcely known. Herein, we describe the preparation of two novel air-stable hetero-halogen complexes, (DMI)2HBr2I and (DMI)2HCl2I (DMI: 1,3-dimethyl-2-imidazolidinone). These complexes were then reacted with alkenes and alkynes, affording hetero-halogen compounds such as bromoiodides and
尽管杂卤素化合物是通用的合成中间体,但它们的一步制备方法鲜为人知。在这里,我们描述了两种新型空气稳定的杂卤素配合物的制备,(
DMI) 2 HBr 2 I 和 (
DMI) 2 HCl 2 I (
DMI: 1,3-dimethyl-2-imidazolidinone)。然后这些配合物与烯烃和
炔烃反应,一步得到
溴碘化物和
氯碘化物等杂卤素化合物。还用这些配合物进行
碘烷氧基化和
碘内酯化。
