碩士 === 國立臺灣師範大學 === 化學研究所 === 90 === Abstract Derivatives of chiral N-salicylideneaminoacidatocopper(Ⅱ) complexes , [Cu(X-sal-L-ser)(L)] , [Cu(X-sal-L-serMe)(L)] , [Cu(X-sal-L-leu)(L)] and [Cu(X-sal-val)(L)] , where L = H2O , were synthesized. These complexes have been characterized by element analysis, UV-vis , CD , IR and EPR spectroscopic measurements. By using three-dimensional X-ray diffraction methods, the crystal and molecular structure of the following complex have been determined. The crystal data of the complex are given below: 1. [Cu(sal-L-ser)(H2O)2] Orthorhombic, space group P212121, with a = 4.7884(6) Å, b = 12.3049(1) Å, c = 19.393(3) Å, V = 1142.6(3) Å3, Z = 4, R = 0.0373, Rw = 0.0918。 2. [Cu(3,5-di-t-butyl-sal-D-val)] Monoclinic, space group C2, with a = 31.234(2) Å, b = 6.7977(4) Å, c = 10.1196(6) Å, V = 2102.7(2) Å3, Z = 4, R = 0.035, Rw = 0.071。 These chiral complexes catalyzed the sulfoxidation of thioanisole with hydrogen peroxide. It is the first report. In addition, these copper(Ⅱ) complexes also can use for epoxidation and oxidation of alcohol. The yield and enantioselectivity of the sulfoxidation products were determined by column, UV-vis, CD and chiral HPLC.
