Synthesis Of Bridged Cyclopentadienyl Compounds

This thesis main focus on designing and synthesizing a series organometallic compounds with indenyl, pyridyl and fluorenyl. Firstly, synthesis of a novel series of triazole ligands with indene and fluorine as basic materials by "Click" reaction, exploring complexation of the ligands with transition metal elements. Secondly, two bis-dentate ligands were synthesized by addition reaction of2-methylpyridine derivatives, containing the silicon-substituted group with a-H free nitriles and then treatment with transition metal salts. Finally, parts of the ligands and organicmetallic complexes were characterized by IR,1HNMR and13CNMR. The main contents included four parts:Chapter1. The development of polyolefins and polyolefin catalysts, and the background and progress of "Click Chemistry".Chapter2. A novel series of Click ligands were synthesized by "Click Chemistry" of indene, benzyl chloride,2-ethynylpyridine, phenylacetylene, propargyl bromide and sodium azide with two reaction routes. These ligands were treatment with zirconium chloride and nickel chloride(DME), and parts of compounds were characterized by X-ray, IR,’HNMR and13CNMR.Chapter3. Synthesis of two bis-dentate ligands by reaction of2-methyl-pyridine, containing the silicon-substituted group with benzonitrile, o-methylbenzonitrile and dimethylamino nitrile. These ligands were treatment with transition metal salts.Chapter4.9-(2-propynyl)-fluorene was synthesized by fluorine and pro-pargyl bromide, which was mixed with benzyl chloride and sodium azide for the preparation of triazole ligand. The ligand was treatment with zirconium chloride, and characterized by IR and NMR spectroscopy.
