How does 2-phenylpyridine participate in electrochemical ortho-arylation?

Label:chem

Topic
This reaction utilizes 2-phenylpyridine with 4-methoxyphenyldiazonium tetrafluoroborate salt and Pd(OAc)2.
Answer
In electrochemical palladium-catalyzed ortho-arylation, 2-phenylpyridine acts as a substrate, reacting with 4-methoxyphenyldiazonium tetrafluoroborate salt in the presence of Pd(OAc)2 , K2HPO4 , and nBu4NF4 to yield the desired mono-arylated product with significant yields (e.g., 75%).
