A novel catalytic system for the asymmetric hydrosilylation of aromatic alkenes is described, which leads to silanes in high yields and with excellent enantioselectivity. The reaction works efficiently for a variety of substituted aromatic alkenes, giving access after Tamao oxidation to almost optically pure benzylic alcohols in high yields.
