Dioxygen-triggered oxidative cleavage of the C–S bond towards C–N bond formation

Research on the cleavage of C–C bonds has been well developed. By comparison with this, the activation of C–S bonds remains challenging. Herein, dioxygen-triggered oxidative cleavage of C–S bonds has been achieved, delivering a series of N-containing heterocyclic compounds that are frequently found in pesticides and pharmaceuticals. Additionally, the potential utility of this protocol was further demonstrated by a gram-scale experiment. Mechanistically, dioxygen plays a key role in the cleavage of C–S bonds towards C–N bond formation.
