A one-pot, Cu-catalyzed direct C–H arylselenation protocol using elemental Se and aryl iodides was developed for nitro-substituted, N-alkylated pyrazoles, imidazoles and other heterocycles including 4H-chromen-4-one. This general and concise method allows one to obtain a large number of unsymmetrical heteroaryl selenides bearing a variety of substituents. The presence of the nitro group was confirmed
针对硝基取代的N-烷基化吡唑、咪唑和包括 4 H -chromen-4-one 在内的其他杂环,开发了一种使用元素 Se 和芳基碘化物的一锅铜催化直接 C-H 芳基硒化方案。这种通用而简洁的方法允许获得大量带有多种取代基的不对称杂芳基硒化物。确认硝基的存在对于 C-H 活化至关重要,也可用于进一步的功能化和操作。还使用开发的合成方案合成了几个杂环化苯并硒嗪的例子。

Pd- or Ni-catalyzed CH arylation of 4-nitroimidazole derivatives directed by a manipulable nitro group was developed. The reaction tolerates a wide range of substituted aryl halides and 4-nitroimidazoles. The experiments indicated that the nitro group has influence on regioselectivity of the reaction. In addition, we have shown that the efficiency of the SuzukiMiyaura cross-coupling reaction of nitroimidazoles is slightly lower in comparison to the direct CH arylation. The exploration of the chemical potential of the nitro group and a putative reaction mechanism are discussed.
