  A transition-metal-free indole synthesis using radical coupling of 2-halotoluenes and imines via the later-stage C–N bond construction was reported for the first time. It includes an aminyl radical generation by C–H cleaving addition of 2-halotoluenes to imines via the carbanion radical relay and an intramolecular coupling of aryl halides with aminyl radicals. One standard condition can be used for
