Abstract The CuCl/NaO t -Bu/BINAP system was found to efficientlycatalyze the hydrosilylation of aryl alkyl ketones with excellent enantioselectivities by using phenyl methylsilane as a stoichiometric hydride source. High enantiomeric excesses (up to 97%) and excellent yields (up to 99%) were obtained.
