The method is promoted by diorganyl diselenides and hydrogen peroxide. In this process, diorganyl diselenides are sacrificially activated to generate reactive selenium species. These species enable alkyne functionalization, followed by ring closure and carbonyl insertion. Unlike classical approaches, the chromenone carbonyl group is generated <em>in situ</em> during cyclization, removing the need for pre-installed carbonyl functionalities. A broad range of diorganyl diselenides and substituted arylpropargyl ethers were evaluated. The protocol afforded the desired chromenones in moderate to excellent yields with good functional-group tolerance. Crossover and control experiments demonstrate that the selenium atom at the C3 position of the chromenone framework comes exclusively from the externally added diorganyl diselenide. It does not originate from the prefunctionalized substrate. Although the diselenide is used sacrificially, it is fully regenerated and recovered at the end. This highlights the protocol's sustainability and atom-economical nature. Mechanistic studies support a predominantly radical pathway for selenium-mediated cyclization.
