Nonafluorobutanesulfonyl azide is an efficient, shelf-stable and cost-effective diazo transfer reagent for the synthesis of azides from primary amines. The reagent can also be successfully applied to the one-pot regioselective synthesis of 1,2,3-triazoles from primary amines by a sequential diazo transfer and azide–alkyne 1,3-dipolar cycloaddition process catalyzed by copper. The cycloaddition step
九氟丁烷磺酰基叠氮化物是一种高效,易保存且经济高效的重氮转移试剂,用于由伯胺合成叠氮化物。该试剂还可以成功地用于通过连续重氮转移和铜催化的叠氮化物-炔烃1,3-偶极环加成反应过程,从伯胺一锅区域选择性合成1,2,3-三唑。环加成步骤可以分子间或分子内方式进行,分别得到1,4-或1,5-二取代的三唑。铜催化下非典型的1,5-区域选择性是分子内形式使用的氨基炔基底物的几何约束的结果。九氟丁烷磺酰基叠氮化物提供了一种更好的替代方法,可以替代众所周知的和最常用的三氟甲磺酰基叠氮化物。
