In this work, the use of N-acyloxybenzamides as efficient acyl nitrene precursors under photoredox/iron dual catalysis is reported. The resulting acyl nitrenes could be captured by various types of C–H bonds and S- or P-containing molecules. Mechanism investigations suggested that the formation of the acyl nitrene from the N-acyloxybenzamide occurs by a photoredox process, and it is believed that in
在这项工作中,报道了在光氧化还原/铁双重催化下使用N-酰氧基苯甲酰胺作为有效的酰基氮烯前体。由此产生的酰基氮烯可以被各种类型的 C-H 键和含 S 或 P 的分子捕获。机理研究表明,由N-酰氧基苯甲酰胺形成酰基氮烯是通过光氧化还原过程发生的,并且认为在该氧化还原过程中,N-酰氧基苯甲酰胺的氧化 N-H 键断裂发生在还原性 N-O 键断裂之前N-酰氧基苯甲酰胺。
