Herein, a disulfide-catalyzed electrophilic iodination of aromatic compounds using 1,3-diiodo-5,5-dimethylhydantoin (DIH) has been developed. The disulfide activates DIH as a Lewis base to promote the iodination reaction in acetonitrile under mild conditions. This system is applicable to a wide range of electron-rich aromatic compounds, including acetanilide, anisole, imidazole, and pyrazole derivatives
在此,已经开发了使用1,3-二碘-5,5-二甲基乙内酰脲(DIH)的二硫化物催化的芳香族化合物的亲电子碘化。在温和条件下,二硫化物激活DIH作为路易斯碱,从而促进乙腈中的碘化反应。该系统适用于多种电子富集的芳族化合物,包括乙酰苯胺,苯甲醚,咪唑和吡唑衍生物。
