Regiodivergent benzoylation of 2-methoxynaphthalene with benzoyl fluoride is presented using either Friedel–Crafts-type chemistry to give selectively the 1-isomer or cooperative NHC/photoredox catalysis to afford the 4-isomer exclusively. Along with arenes, regiodivergent aroylation also works for heteroarenes.
2-甲氧基萘与苯甲酰氟的区域发散性苯甲酰化使用弗里德尔-克来福特型化学选择性地产生 1-异构体或协同 NHC/光氧化还原催化专门产生 4-异构体。与芳烃一样,区域发散芳酰化也适用于杂芳烃。
