Detailed in this report is the enantioselective synthesis of 1,1-diarylalkanes, a structure found in a range of pharmaceutical drug agents and natural products, through the employment of copper(I) hydride (CuH) and palladium (Pd) catalysis. Judicious choice of ligand for both copper and palladium enabled this hydroarylation protocol to work for an extensive array of aryl bromides and styrenes, including β-substituted vinylarenes and six-/five-membered heterocycles, under relatively mild conditions.
