Synthesis And Characterization Of Phosphorus Imide Compounds And Metal Complexes

In recent years, supramolecular polymeric compounds and coordination polymers has been widely applied in various fields, such as information, environment, life, nano, physics, energy source science etc. The synthesis of above compounds with novel structure and unique properties has become one of the hotspot in chemistry. Based on the knowledge of literature, the concepts, bonding theory and experimental methods were summarized, and the potential development was prospected.The synthetic process of reactions of the addition reaction of a-hydrogen-free nitriles with LiN(SiMe3)2, followed by metathetical reaction gave various reaction products. The reactions of LiN(SiMe3)2 with a-hydrogen-free nitriles,3-cyanopyridine, o-tolunitrile,1,3-dicyanobenzene nitriles,1,2-dicyanobenzene nitriles were carried out, followed the metatheses of diphenylphosphinic chloride. Total of six compounds were prepared, one of them is the charge assisted hydrogen bond supramolecular polymeric compound 2a, the other five are phosphorus imine compounds 2b, 2d,2e,2f,2g. The crystal structure of these compounds had been determined by X-ray single crystal diffraction. The synthesis mechanism of the phosphorus imine compounds were discussed.The synthesis of three fibrous compounds 3 a,3b and 3c was described. These fibrous compounds were prepared by the various raw material with the solvent thermal method.At the end of the thesis, the contents of this research were summarized and the future syntheses and properties about phosphorus imines and coordination polymers were programmed.
