A series of mono- and bis-metallated [2]rotaxanes has been prepared using a CuAAC âclickâ protocol that is compatible with metal-coordinated building blocks and ligands; the methodology provides a general means for appending a metal ion or complex to an organic scaffold via Cu(I)-catalysed âclickâ chemistry, even when the molecule contains redox-active or kinetically labile metals or vacant ligand sites.
使用与金属配位结构单元和配体兼容的 CuAAC“点击”方案制备了一系列单金属化和双金属化 [2] 轮烷;该方法提供了一种通过 Cu(I) 催化的“点击”化学将金属离子或络合物附加到有机支架上的通用方法,即使分子含有氧化还原活性或动力学不稳定的金属或空配位点。
