Catalytic meta-selective C-H functionalization to construct quaternary carbon centres

A catalytic meta-selective C-H functionalization of 2-phenylpyridines using a range of tertiary halides is described. The protocol is simple to perform and usees commercially available reagents to construct challenging quaternary carbon centres in a regioselective manner. Preliminary studies suggest the C-H functionalization proceeds trhough a radical process directed via a remote sigma activation
