Synthesis And Characterization Of Aromatic Amidinate Ionic Supramolecular And Circular Organophosphorus Compounds

The theory and application research of organophosphorus is one of the important sources of the modern chemistry development. Based on the theory of phosphorus chemical knowledge, the self-assembly polymeric network of amidinium cations and diphenylphosphinate anions could be formed from the oxidative cleavage of N-P compounds. These π-electron-rich phosphorus-nitrogen compounds had been known as the potential precursors for inorganic polymers with unusual properties, and led to considerable interest in their syntheses and coordination chemistry toward transition metals.In this project, a series of charge-assisted supramolecular polymeric compounds and circular organophosphorus compounds were synthesized. The structure-function relationships of these compounds were investigated.In this paper, the research focused on the interaction of a-hydrogen-free nitriles with LiN(SiMe3)2followed the addition of diphenylphosphinic chloride gave the ionic supramolecular polymeric compounds or circular nitrogen phosphorus products. The molecular structures of these new compounds were characterized by X-ray single diffraction and NMR. In addition to these five novel compounds, some pesticides intermediate compounds were also prepared and characterized by LCQ, NMR. The crystal structure of an intermediate was obtained.Part1:The development of study and application of the organophosphorus chemistry, charge assisted hydrogen bond supramolecular polymeric chemistry was introduced. The subject and progress of this work was summarized.Part2:Benzonitrile,2-,3-,4-cyanopyridine and1,3-dicyanobenzene using as a starting material were reacted with LiN(SiMe3)2, followed by diphenylphosphinic chloride, five novel nitrogen phosphorus compounds and five charge assisted hydrogen bond supramolecular polymeric compounds were produced. The synthesis and characterization of circular organophosphorus compounds2b and2d,2h, P4+compound2f and new circular organic compound2n was described. The fluorescence and ultraviolet properites of the compounds was reported.Part3:The synthesis and characterization of sulfosulfuron and pirimicarb derivatives3b,3d,3h were reported. And one of the intermediate was confirmed by single crystal structure.Finally, the content of part2and3was summarized. The potential application of circular organophosphorus compounds and the possible synthetic method of P4+compounds were reviewed.
