a variety of scientific disciplines, including medicinal chemistry. In this Article, we describe a method for the catalytic enantioselective synthesis of tertiaryalkyl fluorides through Negishi reactions of racemic α-halo-α-fluoroketones, which represents the first catalyticasymmetric cross-coupling that employs geminal dihalides as electrophiles. Thus, selective reaction of a C–Br (or C–Cl) bond
