SO(4)()(-) generated by the Fenton redox system S(2)O(8)(2)(-)- Fe(2+) induces a novel anionic, transannular, self-terminating, oxidative radical cyclization in the reactions with the ten-membered cycloalkyne 1 and the cycloalkynone 7, yielding the bicyclic ketones 5 and 6 or the alpha,beta-epoxy ketones 8 and 9, respectively. In these reactions SO(4)()(-) acts as an oxygen transfer reagent and can thus be considered as a donor of atomic oxygen in solution.
由芬顿氧化还原体系S₂O₈²⁻ - Fe²⁺产生的SO₄⁻*在与十元环炔烃1和环炔酮7的反应中引发了一种新型的阴离子型、跨环、自终止的氧化自由基环化反应，分别生成双环酮5和6或α,β-环氧酮8和9。在这些反应中，SO₄⁻*作为氧转移试剂，因此可被视为溶液中原子氧的供体。
