内容記述 |
We report the direct C(sp3)single bondH bond alkylation using interfacial H2O-covered, Ag nanoparticle-loaded TiO2 (H2O@Ag/TiO2) semiconductor photocatalyst, where H2O catalyst induces hydrogen atom transfer (HAT) without wasteful by-products. For the efficient and selective transformation, it is critical to use a mixed solvent system composed of CH3CN and H2O in an appropriate ratio and to employ relatively electrophilic alkenes as alkylating agents. A wide range of ethers were alkylated selectively at their α-C(sp3)single bondH bonds adjacent to the oxygen atoms in good to excellent yields, regardless of their water affinities (water-miscible or poorly water-soluble), molecular frameworks (cyclic or acyclic), or physical states (liquid or solid). Cyclohexane with no ethereal oxygen, which is almost entirely immiscible with water, also underwent the C(sp3)single bondH alkylation under a similar H2O@Ag/TiO2-photocatalyzed system. |
