  一些新的1 H-吡唑衍生物的制备和结构

  摘要：

  一些新的3,5-二芳基-1 H-吡唑是由芳基甲基酮经克莱森与芳香族酯缩合制备的，然后与一水合肼环化。通过IR，1 H NMR光谱，质谱和元素分析确认了它们的结构。给出了3（5）-（4-叔丁基苯基）-5（3）-（4-甲氧基苯基）-1H-吡唑（2b）的X射线结构。结果表明，化合物2b以互变异构体I和II存在，其分子通过N–H··N分子间氢键连接，形成由互变异构体I和II组成的环状二聚体。

  A facile and efficient copper‐promoted oxidative intramolecular C–H amination of hydrazones for the synthesis of 1H‐indazoles and 1H‐pyrazoles was developed using a tracelessly cleavable directing group. This reaction is characterized by its mild conditions, operational simplicity, readily available reagents, and excellent yields. A tentative mechanism for Cu‐mediated C–H‐oxidative amination was proposed
