摘要: A chiral diamine-based homogeneous cationic rhodium catalyst was developed and two heterogeneous catalysts were obtained via the encapsulation of within Me-SBA-15 Me-SBA-16. All these presented excellent catalytic activities high enantioselectivities in ultrasound-promoted asymmetric transfer hydrogenation aromatic ketones represent a successful use ion-pair immobilization strategy. More importantly, functionality Me-SBA-16 had an obvious recyclability, which recycled could be reused nine times without significantly affecting its enantioselectivity, showing good potential industrial application.
