The combination of allene gas with inexpensive and environmentally benign hydrosilanes enables enantioselective ketone allylation reactions without stoichiometric quantities of an allylmetal reagent. This process is catalyzed by copper salts and commercially available ligands, operates without specialized equipment or pressurization, and tolerates a broad range of functional groups.
