Photoinduced HCl-Mediated Cross-Dehydrogenative Coupling of Quinolines with Alcohols and Ethers.

Via light irradiation, cross-dehydrogenative coupling of quinolines with alcohols and ethers was achieved under mild conditions. A stoichiometric amount of HCl and room temperature were necessary to promote the reaction. A green Minisci-type cross-dehydrogenative coupling reaction was performed without an oxidant or a transition-metal catalyst.
