complexes of monodentate phosphoramidites efficiently promote asymmetric arylation of N‐azaaryl aldimines with arylboroxines. DFT calculations and experiments support an elementary step of 1,4‐insertion in the reaction pathway, a step in which an aryl‐copper species adds directly across four atoms of C=N−C=N in the N‐azaaryl aldimines.
单齿亚磷酰胺的铜络合物可有效地促进N-氮杂芳基醛亚胺与芳基硼氧烷的不对称芳基化。DFT计算和实验支持1,4-插入在反应途径的基本步骤,一个步骤,其中芳基-铜物质增加了C = N-C = N的直接跨四个原子在Ñ -azaaryl醛亚胺。
