Reductive con-PETs, where either a solvated electron is generated upon excitation of a radical anion in a chemical variant of the photoelectric effect or the excited single reduced photocatalyst transfers one electron directly to the substrate, allow difficult reactions such as reduction of aryl and alkyl halides or aromatic systems under mild conditions. By utilizing the excited state chemistry of Nphenylphenothiazine the photocatalytic redox window of the con-PET approach could be expanded. Recently, deazaflavins have been synthesized guided by mechanistic understanding that utilize the internal heavy atom effect for more efficient con-PET and that achieve reductive powers comparable to lithium. However, the full potential of the con-PET systems where two photons of visible light are cumulatively used to access oxidative powers of ≫ +3 V vs. SCE for synthesis has yet to be realized. Here, we report the first successful attempt in this direction.
