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
