determined by single-crystal X-ray diffraction. The complex is highly stable, active and selective toward the copper-catalyzed azide-alkyne cycloaddition, working in neat conditions and in the absence of bases at room temperature. Substrate scope was assessed by testing several different alkynes and azides. In most cases the corresponding 1,4-disubstituted-1,2,3-triazoles were isolated in high yields.
在配位球中与 2,6-二甲基苯基异氰化物的三配位均配 Cu(I) 配合物很容易合成和分离为四氟硼酸盐。该化合物的结构由单晶X射线衍射确定。该配合物对铜催化的叠氮化物-炔烃环加成反应具有高度稳定性、活性和选择性,可在纯净条件下和室温下无碱条件下工作。通过测试几种不同的炔烃和叠氮化物来评估底物范围。在大多数情况下,相应的 1,4-二取代-1,2,3-三唑以高产率分离。
