Aryl halides can be easily transformed in a one-pot procedure into 4-aryl-1,2,3-triazoles with palladium/copper-catalyzed Sonogashira-click reaction sequence, using trimethylsilylacetylene as acetylene surrogate.
芳基卤化物可以通过一步法操作容易地转化为4-芳基-
1,2,3-三氮唑,该过程利用了
钯/
铜催化的Sonogashira-点击反应序列,并以三甲基
硅基
乙炔作为
乙炔替代物。
