Palladium‐Catalyzed Silver‐Mediated α‐Arylation of Acetic Acid: A New Approach for the α‐Arylation of Carbonyl Compounds.

A new approach for the α-arylation of acetic acid through Pd-catalyzed silver-mediated direct CH arylation of acetic acid with aryl iodides was developed. This protocol provided a straightforward method for the synthesis of a diverse set of α-phenylacetic acids.
