Thioxanthylium-based organophotoredox catalysts that operate under irradiation with green light have been developed. These catalysts present high excited-state reduction potentials (E0′(C?/C?) = +1.79–1.94 V vs SCE). They

Horibe, Takahiro,Ohmura, Shuhei,Ishihara, Kazuaki
, p. 1877 - 1881 (2019)
This paper describes the isolation and characterization of an aromatic radical cation generated by FeCl3. X-ray crystallographic analysis and kinetic studies reveal the mechanism of the generation of aromatic radical cation. In the solid state,
Radical Cation Diels-Alder Reactions by TiO2 Photocatalysis

Radical cation Diels-Alder reactions by titanium dioxide (TiO2) photocatalysis in lithium perchlorate/nitromethane solution are described. TiO2 photocatalysis promotes reactions between electron-rich dienes and dienophiles, which would otherwise be difficult to accomplish due to electronic mismatching. The reactions are triggered by hole oxidation of the dienophile and are completed by the excited electron reduction of the radical cation intermediate at the dispersed surface in the absence of any sacrificial substrate.
Benign catalysis with iron: Facile assembly of cyclobutanes and cyclohexenes: Via intermolecular radical cation cycloadditions

The iron(III)-polypyridyl complex and its derivatives showed sufficient oxidizing potential to act as a one-electron oxidant, producing radical cations from olefins and promoting the efficient radical cation [2 + 2] and [2 + 4] cycloaddition reactions. Subsequent chain propagation afforded trisubstituted cyclobutane or cyclohexene derivatives, and this facile route enables the replacement of rare metals with sustainable, green, and inexpensive iron in radical cation cycloadditions.
