在此,我们报告了在 DBU 作为强碱存在下有效合成铜 (II) 酞菁。这些合成的铜 (II) 酞菁被用作敏感化合物(包括无金属卟啉)在室温温和反应条件下发生点击反应的催化剂。此外,我们开发了一种一锅法,用于苄基卤化物与不同炔烃的点击反应,收率良好。反应在室温至 40 °C 下进行并产生 83-99% 的产物。反应在 DMSO 溶剂中进行。目前的反应条件为铜 (II) 酞菁提供了一种高效便捷的催化剂,可用于不同的富电子和缺电子底物,包括大环化合物。缺电子底物和空间位阻较小的底物提供了更好的结果。催化剂很容易通过简单的过滤技术从反应中分离出来,并且可以重复使用多达 5 次,而不会显着降低其催化活性。 图形概要
recoverable and reusable heterogeneous catalyst can be used in the click synthesis of 1,2,3-triazoles via a one-pot three-component reaction of boracic acid, terminal alkynes, and sodium azide at roomtemperature in water. FT-IR, XRD, SEM, XPS, TG, and ICP-AES techniques were used to characterize the catalyst. In general, this reaction, with the aid of this new catalyst, afforded the corresponding products

1,2,3-Triazoles have been extensively studied as compounds possessing important biological activities. In this work, we describe the synthesis of ten 2-(1-aryl-1H-1,2,3-triazol-4-yl)propan-2-ols via copper catalyzed azide alkyne cycloaddition (CuAAc or click chemistry). Next theinvitroantifungalactivity of these ten compounds was evaluated using the microdilution broth method against 42 isolates

N1/N2-substituted 2-(NH-1,2,3-triazol-4-yl)pyridines) were found to be superior ligands for CuI-catalyzed azide-alkyne cycloaddition (CuAAC) reactions. Low catalyst loadings, short reaction times, facile catalyst recyclability, ambient temperature, and open-flask conditions made this catalytic system very practical. The iodide anions could form iodine bridges to construct stable dinuclear Cu(I) complexes with these
吡啶基-三唑配体系统(包括N 2 -2-吡啶基1,2,3-三唑和N 1 / N 2取代的2-(NH(1,2,3-三唑-4-基)吡啶被发现是CuI催化的叠氮化物-炔烃环加成(CuAAC)反应的优良配体。催化剂负载量低,反应时间短,催化剂易于回收利用,环境温度和开瓶条件使该催化系统非常实用。碘化物阴离子可形成碘桥,与这些配体一起构建稳定的双核Cu(I)配合物,这是实现高催化活性的关键。虽然CuBr和CuCl不适合该配体系统,因为Br和Cl原子的尺寸不合适,无法形成相应的双核Cu(I)配合物。
