The photocatalytic coupling of ethers is uncommon because of the challenges in breaking C–O bonds and low selectivity. Herein, we report a visible light-mediated deoxygenation homocoupling of benzyl pyridyl ethers via their pyridium salts. This approach enables C(sp3)–O bondhomolysis under mild conditions. Mechanistic experiments support the radical nature of the reaction. This method is highly compatible
