Ruthenium catalysts enabled C-Hbond functionalizations on arenes with challenging secondary alkyl halides. Particularly, ruthenium(II) biscarboxylate complexes proved to be the key to success for direct alkylations with excellent levels of unusual meta-selectivity. The direct alkylations occurred under mild reaction conditions with ample scope and tolerated valuable functional groups. Detailed mechanistic

synthesis via C–N bondactivation remains underdeveloped. We herein describe a novel ruthenium-catalysed and directing-group assisted protocol for the synthesis of meta-alkylated arenes via dual C–H and C–N activation. Bench-stable and easily handled redox-active Katritzky pyridinium salts derived from abundant amines and aminoacid species were used as alkyl radical precursors. This catalytic reaction

Ruthenium‐catalyzedmeta‐C−H activation of arenes at roomtemperature is reported to proceed under blue‐light irradiation. A variety of heteroarenes are compatible with this photochemical process, which leads to the corresponding meta C−C coupling products in good to very good yields. Initial mechanistic studies suggest a single‐electron transfer process occurs between a photoexcited RuII‐cyclometalated
