我们报告了叠氮基三氟甲烷(CF 3 N 3)和更长的全氟化碳链类似物(R F N 3; R F = C 2 F 5,n C 3 F 7,n C 8 F 17)的有效且可扩展的合成,这使CF 3和全氟烷基直接插入三唑环系统。在铜(I)催化的叠氮化物-炔烃环加成反应(CuAAC)中,叠氮全氟烷烃与末端炔烃显示出良好的反应性,从而获得稀有且稳定的N全氟烷基三唑。叠氮全氟烷烃具有热稳定性,其制备效率对于发现计划应具有吸引力。
New supportedcatalysts for the Huisgen’s [3+2] azide‐alkyne cycloaddition have been prepared by immobilization of copper species on commercially available polymeric matrixes incorporating the 1,5,7‐triazabicyclo[4.4.0]dec‐5‐ene (TBD) template. The synergic exploitation of the exceptional copper chelating ability and basicity profile of the TBD framework, in addition to ensuring effective immobilization

Abstractmagnified imageA library of 1,4‐disubstituted 1,2,3‐triazoles was synthesized using a copper flow reactor. Organic azides, generated in situ from alkyl halides and sodium azide, were reacted with acetylenes using the copper‐catalyzed Huisgen 1,3‐dipolar cycloaddition. This process eliminates both the handling of organic azides and the need for additional copper catalyst and permits the facile preparation of numerous triazoles in a continuous flow process.
