- Photoredox Catalysis in Organophosphorus Chemistry
Kai Luo, Wen-Chao Yang and Prof. Dr. Lei Wu
Version of Record online: 20 JAN 2017 | DOI: 10.1002/ajoc.201600512
Soak up the sun! This review describes recent advances in the synthesis of organophosphorus compounds by employing methods such as photoredox catalysis, transition-metal complex/photoredox dual catalytic systems that incorporate phosphine ligands, and photoredox catalysis in the presence of organophosphorus compounds as organocatalysts.

Trisilatruxene and trioxatruxene, respective sila- and oxa-analogues of truxene, were synthesized by employing a new intramolecular triple cyclization strategy. These compounds together with hexamethyltruxene display long-lived phosphorescence with the lifetime of 4.4–16.4 s at a low temperature. The long lifetimes are attributable to the symmetry-forbidden T1S0 transitions, being essentially linked with the C3-symmetric structures.
- Solvent-Controlled Enzyme-Catalyzed Friedel–Crafts Reactions of Indoles and Isatins by Using α-Chymotrypsin
Jing-Wen Xue, Jun-Tao Guo, Prof. Dr. Yan-Hong He and Prof. Dr. Zhi Guan

Cattle prod: Friedel–Crafts reactions between isatins and indoles catalyzed by α-chymotrypsin from bovine pancreas (BPC) afforded 3-hydroxy-oxindoles or 3,3-bis(indol-3-yl)indolin-2-ones, depending on the protic/aprotic nature of the solvent used.
- Metal-Free Visible-Light-Induced Trifluoromethylation Reactions
Gwi-Rim Park, Yeojin Choi, Dr. Myung Gil Choi, Prof. Dr. Suk-Kyu Chang and Prof. Dr. Eun Jin Cho

Colors everywhere! Metal-free visible-light-induced trifluoromethylation reactions of alkenes, alkynes, and N-heterocycles with CF3I in the presence of Nile red, which acted as an organic photosensitizer under yellow LED irradiation, have been developed.
- Synthesis of Dibenzophosphole Oxides from Dibenzothiophene Dioxides and Phenylphosphine by Two Successive SNAr Reactions

SNAr after SNAr: One-pot treatment of dibenzothiophene dioxides with phenylphosphine and KOH in DMSO at ambient temperature provides the corresponding dibenzophosphole oxides after oxidative workup. Substitution of the endocyclic SO2 unit with PPh could proceed via an intermolecular SNAr reaction of the dioxides with potassium phenylphosphide followed by another SNAr reaction in an intramolecular fashion.
