Visible?Light Promoted C–O Bond Formation with an Integrated Carbon Nitride–Nickel Heterogeneous Photocatalyst

Ni-deposited mesoporous graphitic carbon nitride (Ni-mpg-CNx) is introduced as an inexpensive, robust, easily synthesizable and recyclable material that functions integrated dual photocatalytic system. This overcomes the need of expensive photosensitizers, organic ligands additives well limitations catalyst deactivation in existing photo/Ni catalytic cross-coupling reactions. The Ni-mpg-CNx demonstrated for C–O coupling between aryl halides aliphatic alcohols under mild condition. reaction affords ether product good-to-excellent yields (60–92 %) with broad substrate scope, including heteroaryl bearing electron-withdrawing, -donating neutral groups. heterogeneous can be recovered from mixture reused over multiple cycles without loss activity. findings highlight exciting opportunities catalysis promoted by a fully
