Iron-Catalyzed Photoredox Decarboxylative Hydroalkylation with Alkynes and Alkenes

A photocatalyzed decarboxylative hydroalkylation approach has been developed, providing efficient and stereoselective access to synthetically challenging <i>Z</i>-configured allylamine derivatives from carboxylic acids and alkynes. The reaction is mediated by an iron catalyst, offering a green, environmentally benign, and highly atom-economical process. Moreover, this protocol can be extended to the reaction with alkenes to furnish arylamines and aryl ethers. Overall, this strategy establishes a versatile synthetic platform for the functionalization of unsaturated hydrocarbons.
