Phenols are important organic molecules because they have found widespread applications in many fields. Herein, an efficient and practical approach to prepare phenols from benzoic acids via simple organic reagents at room temperature is reported. This approach is compatible with various functional groups and heterocycles and can be easily scaled up. To demonstrate its synthetic utility, bioactive molecules

based on a tracelessdirectinggroup relay strategy. In this process carbon dioxide is used as a transient directinggroup which facilitates a palladium catalyzed arylation meta to the phenol hydroxyl group with iodoarenes. This transformation proceeds with complete meta-selectivity and is compatible with a variety of functional groups both in the phenol and in the iodoarene coupling partner.
