AbstractA chemoselective, palladium‐catalyzed, ligand‐directed ortho‐CH chlorination and acylation process has been developed, exhibiting high regioselectivity for 2‐arylpyridines bearing a meta‐substituent. Worthy of note is the fact that arylmethyl chlorides as new, readily available, and inexpensive reagents can selectively be utilized as chlorine or acyl sources.magnified image
