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 highly efficient (2–4 h) and regioselective (100 %) transformation using light‐emitting diode (LED) lamps and natural sunlight
太阳来了:通过可见光驱动的光氧化还原催化建立了烯烃的邻位双官能化,即氧三氟甲基化。明智地选择CF 3信号源是关键。可以使用发光二极管(LED)灯和自然阳光在这种高效(2-4h)和区域选择性(100%)转化中使用亲核试剂,例如水,醇和羧酸。SET =单电子转移。
