Nickel-Catalyzed Electrochemical Cyclizative Carboxylation of Alkene-Tethered Carbamoyl Chlorides with Carbon Dioxide

Abstract Nickel-catalyzed electrochemical cyclizative carboxylation of alkene-tethered carbamoyl chlorides with atmospheric carbon dioxide in an undivided cell under simple constant current conditions is reported. This reaction is conducted with high efficiency under mild conditions, providing a convenient and green access to valuable 2-oxoindolin-3-ylacetic acids and 2-oxo-tetrahydroquinoline-4-carboxylic acids.
