The copper‐catalyzed formation of C–O bonds by oxidative coupling of benzylic alcohols with ethers was realized in open air. A series of α‐acyloxy ethers were obtained in good yields with aqueous tert‐butyl hydroperoxide as the oxidant.

Copper-Catalyzed Formation of C-O Bonds by Oxidative Coupling of BenzylicAlcohols with Ethers. -A series of -acyloxy ethers are obtained by the title reaction via a radical pathway. This new method is more atom-economic and environmentally friendly than the existing methods. The reactions of steric hindered benzyl alcohol (Ig) with acyclic ethers (VIc) and (VId) show negligible activities (< 5%) (not shown). -(WANG, Q.; GENG, H.; CHAI, W.; ZENG, X.; XU, M.; ZHU, C.; FU*, R.; YUAN, R.; Eur.
