types of catalytic photoredox processes following the reductive quenching cycle (RQC) and the oxidative quenching cycle (OQC), the discussion is focused on organic transformations based on OQC, in particular the trifluoromethylation of olefinic substrates with electrophilic trifluoromethylating reagents furnishing solvolytic addition products and substitution products. It is concluded that catalytic

Here comes the sun: A facile vicinal difunctionalization of alkenes, oxytrifluoromethylation, was established by visible‐light‐driven photoredox catalysis. Judicious choice of the CF3 source is key. Nucleophiles such as water, alcohols, and carboxylic acids can be used in this highlyefficient (2–4 h) and regioselective (100 %) transformation using light‐emitting diode (LED) lamps and natural sunlight
