Couplings between (hetero)arylchlorides and phenols can be effectively promoted by CuI in combination with an N‐aryl‐N′‐alkyl‐substituted oxalamide ligand to proceed smoothly at 120 °C. For this process, N‐aryl‐N′‐alkyl‐substituted oxalamides are more effective ligands than bis(N‐aryl)‐substituted oxalamides. A wide range of electron‐rich and electron‐poor aryl and heteroaryl chlorides gave the corresponding

A class of oxalic diamides are found to be effective ligands for promoting CuI-catalyzed aryl amination with less reactive (hetero)aryl chlorides. The reaction proceeds at 120 °C with K3PO4 as the base in DMSO to afford a wide range of (hetero)aryl amines in good to excellent yields. The bis(N-aryl) substituted oxalamides are superior ligands to N-aryl-N'-alkyl substituted or bis(N-alkyl) substituted
发现一类草酸二酰胺是促进 CuI 催化的芳基胺化与反应性较低的(杂)芳基氯化物的有效配体。该反应在 120 °C 下以 K3PO4 作为碱在 DMSO 中进行,以良好到极好的收率提供范围广泛的(杂)芳基胺。双(N-芳基)取代的草酰胺是优于N-芳基-N'-烷基取代或双(N-烷基)取代的草酰胺的配体。配体中芳环的电子性质和空间性质对其效率都很重要。

modular ligand library, high-throughput experimentation, and rational ligand evolution have led to a novel copper catalyst for the synthesis of phenols with a traceless hydroxide surrogate. The mild reaction conditions reported here enable the late-stage synthesis of numerous complex, druglike phenols.

amide is established to be an effective catalyst system for Goldberg amidation with inferior reactive (hetero)aryl chlorides, which have not been efficiently documented by Cu-catalysis to date. The reaction is well liberalized toward a variety of functionalized (hetero)aryl chlorides and a wide range of aromatic and aliphatic primary amides in good to excellent yields. Furthermore, the arylation of
Cu 2 O / N,N'-双(噻吩-2-基甲基)草酰胺被确立为用较差的反应性(杂)芳基氯化物进行戈德堡酰胺化的有效催化剂体系,迄今为止,Cu催化还没有有效地证明这一点。 。反应很好地放宽了对各种官能化的(杂)芳基氯化物以及各种芳族和脂族伯酰胺的反应,收率非常好。此外,实现了内酰胺和恶唑烷酮的芳基化。本催化体系还完成了分子内的交叉偶联产物。
