2-Allyl-1,2,3-triazoles were prepared by the palladium-catalyzed three component coupling (TCC) reaction of alkynes, allyl methyl carbonate and trimethylsilyl azide. A π-allylpalladium azide complex, which undergoes the 1,3-dipolar cycloaddition with alkynes, is proposed as a key intermediate in the TCC reaction.
2-炔基1,2,3-三唑是通过炔烃,碳酸烯丙基甲基酯和叠氮化三甲基硅烷的钯催化三组分偶联(TCC)反应制得的。提出了一种与炔烃进行1,3-偶极环加成反应的π-烯丙基铝叠氮化物络合物,作为TCC反应的关键中间体。
