The first polystyrene-supported chiral picolyl menthol has been prepared via a selective hydrosilylation route and evaluated for asymmetric catalysis. The new catalyst was efficient and reusable in the test reaction of diethylzinc addition to benzaldehyde at room temperature. The enantioselectivity was comparable with that of the soluble counterpart.
