agents, which requires the development of simple and efficient radiolabeling methods in many cases. As bioisosteres for halogen and carbonyl moieties, nitriles are important functional groups in pharmaceutical and agrochemical compounds. Here, we disclose a mild organophotoredox-catalyzed method for efficient cyanation of a broad spectrum of electron-rich arenes, including abundant and readily available
This work presents a visible-light mediated oxidativecleavage of unstrained C−C(sp3) and C−N(sp3) bonds of nitriles, alcohols (diols), and amines using Acr+-Mes/Selectfluor/DMAP system and O2 as the oxidant.
