The first example of transition-metal-catalyzed ortho/metaselective dual C-H functionalizations of arenes in one reaction is described. In this transformation, ortho-C-H chlorination and meta-C-H sulfonation of 2-phenoxypyri(mi)dines were achieved simultaneously under catalysis by [Ru(p-cymene)Cl2]2. The other reactant, namely, an arylsulfonyl chloride, played the role of both a sulfonation and chlorination reagent. More importantly, the arylsulfonyl chloride was also an oxidant in the process. Mechanistic studies indicated that six-membered ruthenacycles were the key intermediate in the reaction.
