Herein we report a versatile Mizoroki–Heck‐type photoinduced C(sp3)−N bondcleavage 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

example of nickel-catalyzed Heck-type benzylation of aryl olefins with various benzylamines as benzyl electrophiles, and the benzylic C–N bond cleavage was efficiently promoted by the amine–I2 charge transfer complex (CT complex). The combination of low-cost NiCl2 and I2 has been found to facilitate Heck reaction of tertiary benzylamines and alkenes into various benzyl-substituted alkenes in good to
