研究了光氧化还原催化芳香族C-H键与N-芳氧基呋喃盐类苯酚衍生物的芳氧氧基化反应。目前的无过氧光催化体系是一种在温和的反应条件下生成O-中心芳氧基的简便方法。特别是N-3，5-双(三氟甲基)苯基羰氧基稀土盐在红外光催化剂的作用下是一种高效的芳氧基化试剂。
The photoredox-catalyzed aroyloxylation of aromatic C-H bonds with N-aroyloxylutidinium salts giving phenol derivatives has been developed. The present peroxide-free photocatalytic system is a convenient protocol for the generation of O-centered aroyloxy radicals under mild reaction conditions. In particular, N-3,5-bis(trifluoromethyl) phenylcarbonyloxylutidinium salt serves as an efficient aroyloxylating reagent by the action of Ir photocatalysts.
