been investigated in the process. A variety of 1,5-disubstituted triazoles were prepared in low to good yields. Further studies reveal that the corresponding alkynes were produced as intermediates via elimination reaction. Under the same reaction conditions, the reactions of alkyl alkynes with phenyl azide would give 1,5-disubstituted 1,2,3-triazoles.
已经报道了叠氮化物与β-或α-乙烯基溴的一锅碱基介导的反应。在此过程中已研究了碱和溶剂的作用。各种1,5-二取代的三唑以低到好收率的方式制备。进一步的研究表明,相应的炔烃是通过消除反应生成的中间体。在相同的反应条件下,烷基炔烃与叠氮化苯的反应将生成1,5-二取代的1,2,3-三唑。
