| 英文摘要 | polymeric salen-ti(iv) complexes were employed in the enantioselective o-acetyl cyanation of aldehydes with kcn and ac2o. the polymeric catalysts with appropriate crosslinking degree exhibited good activities and enantioselectivities, up to 94% yield and 91% ee were obtained at -20degreesc with 1 mol% of catalyst (based on bimetallic catalytic unit). moreover, the crosslinked polymeric catalyst could be easily recovered and reused for six consecutive runs without obvious decrease in activity and enantioselectivity.
