Copper(I)-Catalyzed Azide-Alkyne Cycloadditions in Ionic Liquids under Amine-Free Conditions

[摘要]：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 (TM)) without addition of free amine. Unlike the previously tested ionic liquids, this solvent led exclusively to the 1,4-disubstituted triazole regioisomer.
