An unprecedented recyclable catalyst system for asymmetric hydroboration.
Immobilised preformed chiral homogeneous catalysts were subjected to catalytic hydroboration of styrene with catecholborane and the activity, regio- and enantioselectivity observed were similar to those found when the corresponding homogeneous catalyst was used, remaining constant for several consecutive runs.
