The Rh(I)-catalyzed direct reorganization of organic frameworks and group exchanges between carboxylic acids and aryl ketones was developed with the assistance of directinggroup. Biaryls, alkenylarenes, and alkylarenes were produced in high efficiency from aryl ketones and the corresponding carboxylic acids by releasing the other molecule of carboxylic acids and carbon monoxide. A wide range of functional

Inexpensive cobalt catalysts enable the first directarylation and benzylation of (hetero)arenes with aryl carbamates, sulfamates, and phosphates with ample scope. The non‐radical CH/COarylation reaction even proved viable at ambient temperature.
