Metal‐Free Visible‐Light‐Promoted Haloazidation/Cyclization of Phenyl‐Linked 1,6‐Enynes with TMSN₃ and NIS/NBS**

Abstract A metal‐ and oxidant‐free procedure for the three‐component haloazidation/cyclization of phenyl‐linked 1,6‐enynes with TMSN 3 and N ‐iodo(bromo)succinimide under the irradiation of visible light was described. Moreover, this reaction involved a radical addition/5‐exo‐dig cyclization/radical coupling process, and realized simultaneous construction of C−N, C−C, and C−X (I, Br) bonds in one step.
