Copper(I) iodide catalyzed cycloadditions of various combinations of structurally diverse organic azides and terminal alkynes were carried out in a commercially available, polyoxygenated ionic liquid (AMMOENG 100™) without addition of free amine. Unlike the previously tested ionic liquids, this solvent led exclusively to the 1,4-disubstituted triazole regioisomer. alkynes - azides - carbohydrates -
在不添加游离胺的情况下,在市售的多氧化离子液体(AMMOENG 100™)中进行结构多样的有机叠氮化物和末端炔烃的各种组合的碘化亚铜(I)催化的环加成反应。与先前测试过的离子液体不同,该溶剂仅产生1,4-二取代的三唑区域异构体。 炔烃-叠氮化物-碳水化合物-铜-环加成
