New N-heterocyclic Carbene Metallic Hg(â…¡) Cyclophanes:Synthesised And The Properties Researched

N-heterocyclic carbenes and their metal complexes wase one of the most popular subjects in modern organicmetallic chemistry. N-heterocyclic carbenes (NHC) and these complexes on catalytic organic chemistry has been widely used. Its build supramolecular complexes cyclophanes which has a special regulation of cavity structure, in imitation of enzyme chemistry, the main object of chemical, the self-assembly, selective catalysis and materials science, etc.So it will have a extensive potential application prospect.In this paper a new type of N-heterocyclic carbene mercury cyclophane metal complexe was synthesized,and a preliminary research on its properties was made.The main works were summarized as follow:(1) Imidazole derivatives and benzoxazole derivatives andβ-halopropionitrile synthesis of new type of N-heterocyclic carbenes. Benzothiazole and benzoxazole react with β-halopropionitrile were studied.(2) Successful synthesised of the three kinds of metal complexes of mercury(II), two of which was cyclophanes. And the three kinds of metal complexes were investigated on the basis of fluorescent and UV/vis spectroscopic titrations, single crystal structure were studied; two cyclophanes compounds on p-Phenylenediamine for molecular recognition researched.(3) Bridging of benzothiazole carbenes and its complexes were synthesized under the solvent-free conditions.And attempt to synthesis double (benzothiazole-2-Ye Lide), mercury (II) complexes.(4) Mercury(II) complexes of various N-Heterocyclic Carbenes derived from benzoxazole-linked cyclophanes:synthesised and properties researched.
