摘要

A palladium(II)/copper oxide (Cu2O)‐catalyzed one‐pot decarboxylative and direct CH arylation of 2‐picolinic acid with aryl bromides has been developed. Various aryl bromides have been shown to be efficient coupling partners in the presence of dimethyl sulfate, furnishing symmetrical 2,6‐diarylpyridines in moderate to good yields.
