a high-yielding copper(I) catalyzed 1,3-dipolar cycloaddition reaction between in situ generated azides and terminal acetylenes. This one-pot, two-step procedure tolerates most functional groups and circumvents the problems associated with the isolation of potentially toxic and explosive organic azides.
通过在原位生成的叠氮化物和末端乙炔之间进行高产率的铜(I)催化的1,3-偶极环加成反应获得1,4-二取代的1,2,3-三唑。这一一锅,两步程序可以耐受大多数官能团,并避免了与潜在毒性和爆炸性有机叠氮化物的分离有关的问题。
