  Nitrones are key intermediates in organic synthesis. Herein, we report the first photo‐redox synthesis of methylene nitrone intermediates from nitroarenes and arylamines. The highly reactive methylene nitrones are in situ trapped by alkenes to afford various isoxazolidines. This three‐component reaction features the use of N,N‐dimethylanilines or N‐aryl glycines as C1 building blocks, which allow for

  硝基是有机合成中的关键中间体。本文中，我们报道了由硝基芳烃和芳基胺进行的光催化还原亚甲基中间体中间体。高反应性的亚甲基硝基酮被烯烃原位捕获，得到各种异恶唑烷。此三组分反应的特征是使用N，N-二甲基苯胺或N-芳基甘氨酸作为C1结构单元，可从简单的起始原料进行一锅形式的正式[1 + 2 + 2]环加成。在温和的条件下，可以以中等至良好的收率获得各种有用的异恶唑烷。机理研究支持通过选择性的N-CH 3键裂解和亚甲基转移形成亚甲基硝酮。

  describes the design, synthesis, and characterization of unique tri-armed imidazole–indole hybrids RA-RE for naked eye detection of fluoride ion in 9:1 DMSO–water at concentration level of 1.5 ppm, which is recommended permissible limit of fluoride ion. Molecular structures of the receptors are so fabricated that both heterocyclic units, namely, indole and imidazole have been rationally used as chromophore

  摘要 本通讯描述了独特的三臂咪唑-吲哚杂化物 RA-RE 的设计、合成和表征，用于肉眼检测 9:1 DMSO-水中的氟离子，浓度为 1.5 ppm，这是推荐的允许限值氟离子。受体的分子结构是这样制造的，以至于两个杂环单元，即吲哚和咪唑已分别被合理地用作发色团和结合单元。在吲哚环的第五位战略性地引入硝基显着增强了受体 RD 的结合能力，使其对氟离子（四丁基铵盐）的选择性高于其他典型的阴离子物质。感知事件可以通过肉眼快速地随着颜色变化而可视化。在紫外-可见光谱研究中，80 nm 的红移很好地证实了这一观察结果。由于 1H NMR 滴定，在 16.1 ppm 处的峰证实了氟离子对咪唑鎓 N-H 的去质子化作用。图形概要
