A one-pot method for the synthesis of 4,5-disubstituted-1,2,3-(NH)-triazoles via carbonylative Sonogashira reaction/1,3-dipolar cycloaddition of terminal acetylenes, carbon monoxide, aryl iodides, and sodium azide was developed. A series of new 4,5-disubstituted-1,2,3-(NH)-triazoles were prepared readily under mild conditions.
一锅法通过羰基Sonogashira反应/末端乙炔,一氧化碳,芳基碘化物和叠氮化钠的1,3-偶极环加成反应合成4,5-二取代-1,2,3-(NH)-三唑发展了。在温和条件下很容易制备出一系列新的4,5-二取代-1,2,3-(NH)-三唑。
