Asymmetric cross-coupling of achiral biaryl ditriflates with aryl Grignard reagents in the presence of 1 equiv of lithium bromide and 5 tool % of palladium complex PdC12[(S)-alaphos], where alaphos stands for (2dimethylamino)propyldiphenylphosphine, gave axially chiral monophenylation products with
