Herein we report a versatile Mizoroki–Heck‐type photoinduced C(sp3)−N bond cleavage reaction. Under visible‐light irradiation (455 nm, blue LEDs) at room temperature, alkyl Katritzky salts react smoothly with alkenes in a 1:1 molar ratio in the presence of 1.0 mol % of commercially available photoredox catalyst without the need for any base, affording the corresponding alkyl‐substituted alkenes in
在本文中,我们报道了一种多功能的Mizoroki-Heck型光诱导的C(sp 3)-N键裂解反应。在室温下在可见光辐射(455 nm,蓝色LED)下,烷基Katritzky盐与烯烃以1:1的摩尔比在1.0 mol%的市售光氧化还原催化剂存在下平稳反应,无需任何碱,提供了相应的烷基取代烯烃,具有良好的收率和广泛的官能团相容性。值得注意的是,Ë / Ž烯烃产物的-选择性可以通过photoredox催化剂的适当选择被控制。
