A copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction for the synthesis of 1,4-disubstituted 1,2,3-triazoles from alkyl diacyl peroxides, azidotrimethylsilane, and terminal alkynes is reported. The alkyl carboxylic acids is for the first time being used as the alkyl azide precursors in the form of alkyl diacyl peroxides. This method avoids the necessity to handle organic azides, as they are
据报道,铜催化的叠氮化物-炔烃环加成反应(CuAAC)可从烷基二酰基过氧化物,叠氮基三甲基硅烷和末端炔烃合成1,4-二取代的1,2,3-三唑。烷基羧酸首次以烷基二酰基过氧化物的形式用作烷基叠氮化物前体。这种方法避免了处理有机叠氮化物的必要性,因为它们是就地产生的,从而使该协议在操作上很简单。Cu(I)催化剂不仅参与烷基二酰基过氧化物的分解以提供烷基叠氮化物,而且催化随后的CuAAC反应以生产1,2,3-三唑。
