Photoredox/Iron Dual-Catalyzed Insertion of Acyl Nitrenes into C–H Bonds
Organic Letters(2022)
摘要
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 this redox process oxidative N–H bond cleavage of the N-acyloxybenzamide occurs prior to reductive N–O bond cleavage of the N-acyloxybenzamide.
