Method for catalytically synthesizing chiral alpha-aryl propionaldehyde by using supported Rh-based heterogeneous catalyst

The invention belongs to the technical field of catalysts, and relates to preparation of a supported Rh-based heterogeneous catalyst and a method for asymmetric carbonyl synthesis of chiral alpha-aryl propionaldehyde from alpha-aryl ethylene, and the heterogeneous catalyst is prepared by loading Rh (III) on a functional skeleton of porous IRMOF-3 in a hot dipping manner, the Rh-based catalyst and a chiral ligand (R)-BINAP form a synergistic catalysis system. The prepared heterogeneous catalyst is highly dispersed in active components, simple and convenient in synthesis route, recyclable, safe and efficient, and has very high heterogeneous aldehyde yield and regioselectivity in catalysis of asymmetric carbonyl synthesis of chiral alpha-aryl propionaldehyde. 本发明属于催化剂技术领域，涉及一种负载型Rh基多相催化剂的制备及α-芳基乙烯不对称羰基合成手性α-芳基丙醛的方法，其中多相催化剂是Rh(Ⅲ)以热浸渍的方式负载于多孔IRMOF-3的功能化骨架上，Rh基催化剂与手性配体(R)-BINAP组成协同催化体系。制备的多相催化剂活性组分高度分散、合成路线简便、可回收循环使用、安全高效，催化不对称羰基合成手性α-芳基丙醛具有很高的异构醛收率与区域选择性。
