Synthesis And Application Of Azaallymetal Compounds And N, N(O)-Bidentate Complexes

In recent years, as the increase of the polyolefin and environmental awareness, the design and synthesis including transition metal catalyst and ring-opening polymerization catalyst of lactide become the hot research areas of the Organometallic Chemistry. Chemists are combining the effective and selectivity and low pollution catalyst.On the basis of the above background and with the help of many relevant literatures, the papers are developed. The experiments are divided into the chapters, the contents as follows: Chapter 1. Introduction to the research background of this thesis:(1) The main polyolefin catalyst; (2) Synthesis and characteristic of azaallyl metal complexes; (3) The study and applications of organic ligands with nitrogen and oxygen atoms and their metal complexes.Chapter 2. Some azaallyl ligands and theirs metal complexes were prepared from o-Tolualdehyde and kinds of amines by means of condensation reaction and dehydrogenation and so on.Chapter 3. Some new chiral ligands were prepared from aldehyde and a-phenylethylamine. The ligands were characterized by NMR Organometallic complexes were synthesized from the reaction of relevant ligand and ZnEt2 or AlMe3. All the organometallic compounds were characterized by NMR and X-ray diffraction analysis.
