Acid brings the oxygen: A general method for palladium‐catalyzed CH oxygenation has been developed for the facile synthesis of a wide range of functionalized phenols with readily available aryl ketones, benzoates, benzamides, acetanilides, and sulfonamides. A trifluoroacetic acid/trifluoroacetic acid anhydride solvent system serves as the oxygen source and is the critical factor for CH activation
