first catalytic process has been developed for the direct synthesis of amides from readily available petroleum by‐products (methylarenes) and amines using an iron catalyst. In this new catalytic reaction, the methylgroup of the methylarene is oxidized to the corresponding aldehyde through non‐directed CHoxidation followed by its oxidative amidation with N‐chloroamine, yielding the carboxylic amide

aminocarbonylation of (hetero)arylhalides is widely applied in the synthesis of amides but relies heavily on the use of precious metal catalysis. Herein, we report an aminocarbonylation of (hetero)arylhalides using a simple cobalt catalyst under visible light irradiation. The reaction extends to the use of (hetero)aryl chlorides and is successful with a broad range of amine nucleophiles. Mechanistic investigations

Various aryl triflates derived from phenols were converted into aryl esters or amides in good yields by a palladium-catalyzed reaction with carbon monoxide and alcohols or amines.

two-step synthesis of structurally diverse 3-aminoindazoles from readily available starting materials was developed. This sequence includes a one-pot synthesis of aminohydrazones through chemoselective Tf2O-mediated activation of tertiary amides and subsequent addition of nucleophilic hydrazides. These precursors then participate in an intramolecularligand-free Pd-catalyzed C–H aminationreaction. The
