Radical C(sp 2 )–H sulfonylation and C(sp 2 )–N bond oxygenation enabling the chemoselective synthesis of 3‐sulfonyl chromones by using enaminones and sulfonyl hydrazines were accomplished. The domino reactions ran well by using molecular iodine without the assistance of any strong oxidant such as a peroxide or a hypervalent metal salt.
