Rhodium‐Catalyzed Electrooxidative C−H Olefination of Benzamides

Metal‐catalyzed chelation‐assisted C−H olefinations have emerged as powerful tools for the construction of functionalized alkenes. Herein, we describe the rhoda‐electrocatalyzed C−H activation/alkenylation of arenes. The olefinations of challenging electron‐poor benzamides were thus accomplished in a fully dehydrogenative fashion under electrochemical conditions, avoiding stoichiometric chemical oxidants, and with H(2) as the only byproduct. This versatile alkenylation reaction also features broad substrate scope and used electricity as a green oxidant.
