Neutral, C2-symmetric S/C/S ligands based on N-heterocyclic carbenes and thioether functionalities were incorporated into transition metal complexes characterised by two direct metal-stereogenic sulfur bonds. This new ligand design was applied to 1,3-dipolar cycloadditions as the first example of the use silver of carbenes in asymmetric catalysis.
基于 N-杂环卡宾和硫醚官能团的中性、C2 对称 S/C/S 配体被引入到具有两个直接金属手性硫键的过渡金属配合物中。这种新的配体设计被应用于 1,3-偶极环加成反应,这是首例在不对称催化中使用银卡宾的例子。
