Abstract

Photo-redox between diphenylphosphine oxide and 10-methylacridinium iodide with visible light in aqueous acetonitrile under argon atmosphere is initiated by single electron transfer from the phosphorus compound to the acridinium salt in the photo-excited state giving diphenylphosphinic acid and 10-methylacridan as the final products. Iodide ion/iodine couple plays a crucial role for transferring an electron in this reaction.
