A noble-metal-free, photo-induced decarboxylative Heck-type coupling of terminal alkenes with alkyl carboxylic acids was achieved in the absence of external oxidants through the synergistic combination of an organo photo-redox catalyst and a cobaloxime catalyst, with H2 and CO2 as the only byproducts. More than 90 olefins across a wide range of functionalities were effectively synthesized with this simple protocol.
