Ruthenium‐catalyzed meta ‐C−H activation of arenes at room temperature 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 Ru II ‐cyclometalated complex and alkyl halides, enabling meta ‐C−H functionalization reaction via carbon‐centered radicals.
