Synthesis And Characterization Of η~3-azaallyl Organometallic Complexes

The polyolefin is a kind of material which is mostly used for the synthesis of resin. Its output is bound up with the level of a country’s industry development closely. The catalyst which was researched and developed in the polyolefin is the point of the research because the reaction condition was limited by the special structure so harsh. It is the main direction to the synthesis of the catalyst which is effective and selectivity such as the catalyst of Ziegler-Natta, metallocene and transitionmetal. The new material of polyolefin was made and the technologic improvement of the catalyzed in the polyolefin was perfect. It’s the top of issue in the field of the organometallic chemistry and materials chemistry.The paper above the background was formulated as follows:Firstly, the η3-azaallyl organometallic compounds were designed and synthetized. Secondly, the β-diketiminato organometallic compounds were designed and synthetized. All compounds were characterized by NMR、X-ray diffraction anlysis. The experiments were divided into three sections, the contents are as follows:Part1:Introduction to the research background of this thesis:(1) The main polyolefin catalyst;(2) Synthesis and characteristic of η3-azaallyl metal complexes;(3) The study and applications of β-diketiminato and their metal complexes.(4) The purpose and significance of this thesis.Part2:Some azaallyl ligands and their metal complexes were prepared from acetone or hypnone and kinds of amines (aniline,2,6-diethylaniline,2,6-diisopropylaniline).All compounds were characterized by NMR and X-ray diffraction anlysis.Part3: Some β-diketiminato were prepared from acetone or hypnone and kinds of amines(aniline,2,6-diisopropylaniline,2,6-diethylaniline) according to the condensation reaction, dehydrogenation and addition with the α-H freed nitrile. The metal complexes were designed recently and the all compounds were characterized by NMR.
