  we report a new route for the synthesis of substituted imidazoles via photocyclization of readily available amines at room temperature. The reaction is achieved by the visible-light-induced C–C/C–N bond coupling and subsequent dehydrogenation reaction over Mo–ZnIn2S4 as a heterogeneous photocatalyst. A wide range of amines were converted into the corresponding tri- and tetra-substituted imidazoles with

  取代的咪唑传统上是通过多种原料的共缩合反应合成的。在这里，我们报告了一种新的途径，用于在室温下通过光环化现成的胺来合成取代的咪唑。该反应是通过可见光诱导的C–C / C–N键偶联以及随后作为非均相光催化剂的Mo–ZnIn 2 S 4进行的脱氢反应来实现的。多种胺被转化为相应的三取代和四取代的咪唑，总收率高达96％。该新反应的简单性，高效性和温和条件的优点将使其能够用于合成转化中。
