A generality-oriented and adaptive α-sulfonylation of alkynes via photoinduced multicomponent radical cross-coupling of terminal alkynes with sulfinates and a variety of alcohols, thiophenols, or selenophenols has been explored. This protocol features mild conditions, good functional group tolerability, broad substrate scope, excellent chemo-, site-, and stereoselectivity, and applicability to late-stage functionalization. It provides a modular platform for the synthesis of value-added structurally diverse α-sulfonyl-containing multisubstituted alkenes from simple precursors.
