An efficient iminyl radical-triggered 1,5-hydrogen-atom transfer/Heck-type coupling cascade has been achieved through visible-light photoredox catalysis. A variety of unactivated C(sp3)-H bonds have been alkenylated efficiently and selectively with easily available alkenes, providing an elegant route to γ-alkenylated ketone.
