A comparison of green methods for the synthesis of -acyl pyrazoles starting from aromatic carbohydrazide derivatives and 1,3-diketones is presented. Special attention was focused on reactions utilizing a ball mill enabling the synthesis of novel pyrazole derivatives with optimal yield and reproducibility. The use of this approach facilitated the synthesis of target compounds exhibiting solid-state luminescent properties attributable to the phenomenon of aggregation-induced emission (AIE). Additionally, efforts were made to prepare thin, luminescent solid-state films, allowing for the assessment of which synthesized compounds may have potential applications in organic electronics.
本文介绍了从芳香族酰肼衍生物和1,3 - 二酮开始合成α-酰基吡唑的绿色方法的比较。特别关注了利用球磨机的反应，该反应能够以最佳产率和可重复性合成新型吡唑衍生物。这种方法的使用促进了具有归因于聚集诱导发光（AIE）现象的固态发光特性的目标化合物的合成。此外，还努力制备薄的发光固态薄膜，以便评估哪些合成化合物可能在有机电子学中具有潜在应用。
