Abstract

Herein, a visible-light-driven synthesis of 1,4-dicarbonyl vinyl sulfones via sulfoxonium ylide homocoupling forming CC bonds, followed by sulfonyl hydrazide alkenylation is disclosed. Mechanistic studies support a sequential single-electron transfer (SET) and radical addition pathway. The method offers a sustainable alternative to conventional alkyne functionalization strategies.
