Metal‐catalyzed cross‐coupling reactions belong to the most important transformations in
organic synthesis. Copper catalysis has received great attention owing to the low toxicity …

Abstract The nondirected C (sp2)− H activation of simple arenes has advanced significantly
in recent years through the discovery of new catalyst systems that are able to perform …

Cu-mediated Ullmann-type cross-coupling has experienced significant advances over the
last century since the seminal publication by Ullmann in 1901. These advances have …

The palladium-catalyzed cross-coupling of amines and aryl (pseudo) halides, now
commonly known as the Buchwald–Hartwig amination, was first reported 25 years ago …

Transformations of aromatic compounds into the corresponding amines, amides, and imides
through carbon–hydrogen (C–H) bond functionalization represent one of the most step-and …

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 …

An operationally simple and general method for copper-catalyzed, aminoquinoline-assisted
amination of β-C (sp2)-H bonds of benzoic acid derivatives is reported. The reaction …

The direct C–H amination of arenes is an important strategy to streamline the discovery and
preparation of functional molecules. Herein, we report an operationally simple arene C–H …

Copper‐catalyzed cross‐couplings of aryl halides and nucleophiles, traditionally called
Ullmann‐type coupling reactions, were initially reported by Ullmann et al. from 1901—1929 …

A transition-metal-free approach was disclosed for intermolecular aryl C–N bonds formation
between phenols and cyclic anilines via cross-dehydrogenative coupling (CDC) amination …
