Abstract
A series of new chiral catalysts of Salen-Ti(OR), complexes were synth esized, which were found to be efficient catalysts for the enantiosele ctive silylcyanation of aldehydes. The enantioselectivities of 22.4%-8 7.1% were obtained by using chiral Salen-Ti(OR)(4) complexes as cataly st. The reaction mechanism was proposed and justified by experiments.
