Uranyl nitrate hexahydrate performs as an efficient photocatalyst in the direct C–H to C–C bond conversion under blue light irradiation via hydrogen atom transfer (HAT). This uranyl salt enables the remarkable smooth functionalization of unactivated (cyclo)alkanes, ethers, acetals, and amides via radical addition onto electrophilic olefins. Dedicated electrochemical measurements on compounds and intermediates
硝酸铀酰六水合物在通过氢原子转移(HAT)的蓝光照射下,在直接C–H到C–C键转换中,可作为有效的光催化剂。这种铀酰盐可通过自由基加成到亲电烯烃上,使未活化的(环)烷烃,醚,乙缩醛和酰胺具有显着的平滑功能。对该过程中涉及的化合物和中间体进行了专门的电化学测量,以支持该机理建议。
