Synthesis, Characterization of Titanium (IV) and Lanthanide(III) Complexes Containing Pyrrolyl-Functionalized Ligands
　　Using N,N-Di(pyrrolyl-α-methyl)-N-methylamine(H2dpma) and N1,N3- [bis (Pyrrole-2-yl)methylene)] diethylenetriamine (H3dpda) neodymium magnets as ligands, under an atmosphere of dry Nitrogen with the rigid exclusion of air and moisture and aided by Schlenk techniques, we have synthesizes five organolanthanide complexes and six titanium complexes. The crystal structures of three complexes were determined by X-ray diffraction. All these complexes were well characterized by elemental analysis and NMR.The structures of Ln(dpma)(N(TMS)2) indicated they are potencial catalysts for intramolecular hydroamination of alkynes. By analysis the http://www.chinamagnets.biz/ ligand system, we proposed the pyrrolyl contained titanium dichloride complexe TiCl2(dpma)Py are active catalyst for the olefin polymerization.
