Mechanistic Insights into the Light-Driven Difunctionalization of Alkenes with a Sulfonyl-Based Reagent: A Catalyst-Free Approach

Visible-light-mediated difunctionalization of nonactivated alkenes offers a sustainable and efficient strategy for constructing diverse molecular frameworks relevant to medicinal chemistry, polymer science, and synthesis of fine chemicals. While established approaches─such as photoredox catalysis, energy transfer (EnT), and ligand-to-metal charge transfer (LMCT)─have demonstrated success, they typically require external photocatalysts to achieve high reactivity. Alternatively, electron donor–acceptor […]
