Synthesis And Structures Of Metal Complexes With Pyridyl

This dissertation focuses on designing and synthesizing a kind of metal complexes with silyl bridged amido-pyridine.two bis-dentate, a kind of tridentate and a complex coordination compound with lithium bearing pyridine were synthesized with 2-methyl-pyridin and 2-aminopyridine. the proposed mechanism of a cyclization aza-silane was studied. A novel cage lithium complex was synthesized by'addition reaction of 2,6-Diisopropylaniline derivatives which contained the substituted silica-base with a-H free nitriles.Four parts are included in this dissertation as follows:Part I:The progress of catalysts used in polymerization and/or oligomerization of ethylene is summarized, especially for former transition metal complexes.Part II:a cyclization aza-silane was synthesized with four methods, and the proposed mechanism was studied here.PartIII:Three metal complexes with silyl bridged amido-pyridine and A complex organic acid ligand lithium compounds were synthesized and characterized by IH NMR apectra and X-ray diffraction patterns.Part IV:A novel cage lithium complex was synthesized by addition reaction of 2,6-Diisopropylaniline derivatives which contained the substituted silica-base with a-H free nitriles ((Me)2NCN) and characterized.
