Visible-light-induced C-H functionalization has emerged as one of the most active research topics in sustainable organic synthesis,which are associated with low energy consumption,concise route and mild conditions.1 Some photoreactions require photosensitizers,such as organic dyes or metal complexes while others can proceed without additional photosensitizers.With our previous experience of visible-light-induced organic transformations in the absence of an external photosensitizer,2 we herein report a visible-light-induced α-position C–H activation and alkynylation of ethers with alkynyl bromides to generate the corresponding α-alkynyl ethers in good yields at room temperature with broad substrate scope in the absence of any external photocatalyst.The value of this efficient and eco-friendly methodology for the synthesis of α-alkynyl ethers has been highlighted via the ability to perform the reaction at room temperature by visible light irradiation protocol.
