Synthesis, Characterization And Catalytic Properties Of Rare Earth Complexes Incorporating Hydroxyl Schiff Base Ligands

In this thesis, we report synthesis, characterization and catalytic properties of rare earth complexes incorporating hydroxyl Schiff base ligands and a Mannich reaction catalyzed by TiCl4. They are expressed in details as follows.In the first part, we reported the synthesis of four complexes of [Y(SAP)(HMDS)(THF)]2 (1)[Sm(SAP)(HMDS)(THF)]2 (2),[Yb(SAP)(HMDS)(THF)]2(3)and [NaSm3(PMAP)5(THF)6](4). Complexes 1, 2 and 3 were obtained by using Ln[(N(SiMe3)2]3 and H2sap (sap = salicylidene-2-aminophenol) as the starting materials. Complex 4 was synthesized from the reaction between Sm[(N(SiMe3)2]3 and H2PMAP (PMAP = 2-pyrrol-2-ylmethyleneamino-phenol). The structures of four complexes were characterized by X-ray crystal diffraction.In the second part, the hydroamination reaction of alkene catalyzed by 1, 2 and 3 were investigated and the mechanism of the reaction was explored.In the third part, TiCl4-catalyzed one-pot Mannich reaction of benzaldehyde, acetophenone and aromatic amines was reported.
