Chiral porous metal–organic frameworks containing μ-oxo-bis[Ti(salan)] units for asymmetric cyanation of aldehydes†
Abstract
Two chiral porous Ti(salan)-based metal–organic frameworks are constructed and are shown to be efficient and recyclable heterogeneous catalysts for asymmetric cyanation reaction of aldehydes, displaying significantly higher enantioselectivity than their homogeneous counterpart.
