Visible light‐promoted and gold‐photoredox‐catalyzed reactions of heteroatom (N, S, Se, O) tethered alkynes with arenediazonium salts selectively proceeded to build vicinal diaryl‐substituted 2 H ‐benzo[ e ][1,2]thiazine 1,1‐dioxides (benzosultams), benzoselenophenes, benzothiophenes, 4 H ‐chromen‐4‐ones (flavones), 3 H ‐indoles, 1 H ‐isochromen‐1‐ones (isocoumarins), and 4 H ‐thiochromen‐4‐ones (thioflavones). Moreover, the utility of functionalized 3 H ‐indoles as precursors for further elaboration has been demonstrated with the switchable and facile preparation of 1 H ‐indoles, 2‐oxindoles, and 3‐oxindolines.
