我们研究了杂硫金属W(Mo)/ S / Cu团簇[NH 4 ] 2 [MS 4 Cu n X n ](M = W,Mo; X = Br,I; n = 2,4,6)作为新型铜( I)Huisgen 1,3-偶极环加成的催化剂。实验表明,硫金属配体可以稳定铜离子并提高其溶解度。有趣的是,这些簇化合物在铜(I)催化的叠氮化物-炔烃环加成(CuAAC)中具有非常不同的催化性能,这可能与其不同的氧化还原电位有关。簇[NH 4 ] 2 [MS 4 Cu 4 I 4业已发现]是一种非常坚固有效的CuAAC催化剂,并在室温下在极性溶剂或无溶剂条件下以优异的产率用于合成多种1,4-二取代的1,2,3-三唑。

Cu(BTC)-MOF catalyzed one-pot, three-component reaction of terminal alkynes, halides and sodium azide to form 1,4-disubstituted-1,2,3-triazoles was investigated. It was conducted in methanol under room temperature with good to excellent product yields. The Cu(BTC)-MOF catalyst could be easily recovered by filtration and be reused at least three recycles with no significant decrease in the yield. The method was demonstrated to be a truly green process with sustainability and economics. (C) 2018 Elsevier Ltd. All rights reserved.

Three-component reaction of alkyl halides, sodium azide with terminal alkynes can be catalyzed by nano-copper particles under ambient conditions. A series of 1,4-disubstituted-1,2,3-triazoles were obtained regioselectively by this one-pot strategy. Nano copper can be reused at least three times without significant deactivation.
