A selective copper-catalyzed hydride addition to propargylic chlorides enables a mild and efficient synthesis of allenes from propargylic chlorides in the presence of diisobutylaluminum hydride. This transformation provides a wide range of functionalized allenes in good to excellent yields with high regio- and stereoselectivities.
