selenides from the sp3-C–H bond of oxindole, tetralone, arylacetamide, and aryl chalcogenide precursors. Sulfones were obtained from sodium sulfinates usingpotassium iodide, tert-butyl hydroperoxide in DMSO, and acetic acid. Sulfides and selenides were prepared from diaryl disulfides or diselenides employing potassium tert-butoxide in DMSO. α-Tetralone underwent concomitant chalcogenation and aromatization
