nitrogenation suffered from simple amidation/amination with limited atom‐economy and is mostly limited to C(sp2)−H substrates. In this work, anthranil was designed as a novel bifunctional aminating reagent for both C(sp2)−H and C(sp3)−H bonds under rhodium(III) catalysis, thus affording a nucleophilic aniline tethered to an electrophilic carbonyl. A tridendate rhodium(III) complex has been isolated as the
C−N Bond formation is of great significance due to the ubiquity of nitrogen‐containing compounds. Here, a mild and efficient RhIII‐catalyzed C(sp3)−H aryl amination reaction is reported. Anthranil is employed as the nitrogen source with 100 % atom efficiency. This C−H amination reaction exhibits broad substrate scope without using any external oxidants.

Efficient, atom-economical, highly regioselective C(sp3)–H bond alkenylation of 8-methylquinoline catalyzed by (Cp*)Co(III) is reported. A well-defined, air-stable, molecular cobalt catalyst, Cp*Co(III), is employed for the first time in C(sp3)–H bond activation. The developed methodology is broadly applicable and tolerates a variety of functional groups, under mild conditions. Experimental and density

A direct, regiospecific, and efficient palladium-catalyzed α-ketoesterification of 8-methylquinoline derivatives to generate α-ketoesters has been discovered. This reaction is conducted at a mild temperature, free of peroxide, and compatible with air, and various α-ketoesters were achieved with good yields. Importantly, this reaction can be easily amplified to gram level using only 1 mol % of the palladium
