| Summary: | 碩士 === 國立高雄大學 === 應用化學系碩士班 === 102 === 1,8-bis(N-heterocyclic carbene) carbazolide ligands react with Ni(OAc)2•4H2O to yield 1,8-bis(N-heterocyclic carbene) carbazolide acetate complexes. Under aerobic condition, reaction of these nickel complexes and organonitriles give nickel cyano compounds. GC-FID, HPLC and LC-MS analysis show the products containing benzaldehyde, benzoic acid, butyl benzoate, benzil and 3-oxo-2,3-diphenylpropanenitrile, which provide useful information for the mechanism of C-CN bond activation. Moreover, 6-methyl-8-(3-methylimidazolium-1-yl)-1,2,3,4-tetrahydrocarbazole diiodide, 8-(3-butylimidazolium-1-yl)-6-methyl-1,2,3,4-tetrahydrocarbazole dibromide and 8-(3-benzylimidazolium-1-yl)-6-methyl-1,2,3,4-tetrahydrocarbazole dibromide are prepared and characterized by 1H NMR, 13C NMR, X-ray diffraction, elemental analysis, and HRMS. Complexation of the above ligands and nickel acetate gives paramagnetic compounds, which might result from the three-coordinate feature of the metal central atom.
