Palladium-catalyzed meta-selective C-H deuteration of a series of substrates, including phenylacetic acids, hydrocinnamic acid, benzylphosphonate, benzylsulfonate, and benzyl and phenyl ethyl alcohol ester, is developed by using a pyridine-based directing template. The template is installed into the substrate through a practical ester linkage. Under mild reaction conditions, a variety of phenylacetic acids containing alkyl, methoxyl, and halo substituents are compatible in the reaction, resulting in high levels of D-incorporation at the meta position.
