Iron-Catalyzed Decarboxylative Olefination of Unstrained Carbon-Carbon Bonds Relying on Alkoxyl Radical Induced Cascade

An iron-catalyzed decarboxylative olefination of unstrained carbon-carbon bonds via alkoxyl radical induced C-C bond cleavage is presented. This protocol features mild conditions (room temperature, redox-neutral), good substrate scope and functional group compatibility, as well as excellent stereoselectivity, thus providing a facile access to the distal alkenyl ketones.
