Copper(II)-Catalyzed ortho-Functionalization of 2-Arylpyridines with Acyl Chlo-rides. — The copper-catalyzed reaction of 2-arylpyridines (I) with acyl chlorides in the presence of tBuOK gives rise to ortho-benzoxylation products (III), whilst the reaction in the presence of Li2CO3 generates ortho-chlorinated derivatives [cf. (IV), (VI)]. — (WANG, W.; PAN, C.; CHEN*, F.; CHENG, J.; Chem. Commun. (Cambridge) 47 (2011) 13, 3978-3980, http://dx.doi.org/10.1039/c0cc05557c ; Coll. Chem. Mater.
