在无水乙醇体系中设计合成了2种配合物:[Cu(L1)Cl2]·0.5C2H5OH(1)和Co(L1)Cl2(2)(L1=1,4-双(吡唑甲基)苯)。通过元素分析、红外光谱、热重、X-射线粉末和X-射线单晶衍射方法对其结构进行了表征,分析了其光谱及结构特征。结构分析表明,配合物1中金属配位数为5,形成四角锥构型,配合物2的中心金属配位数为4,形成了扭曲四面体构型,配体1,4-双(吡唑甲基)苯采取二齿桥联配位模式。通过仿生催化溴化动力学研究,发现上述配合物均表现出潜在的催化溴化活性。
Two kinds of complexes were designed and synthesized in absolute ethanol system: [Cu (L1) Cl2] · 0.5C2H5OH (1) and Co (L1) Cl2 benzene). Its structure was characterized by elemental analysis, IR, TG, X-ray powder diffraction and X-ray single crystal diffraction. The spectra and structural characteristics were analyzed. The structure analysis shows that the coordination number of metal in the complex 1 is 5, forming a quadrangular pyramid conformation, and the central metal coordination number of the complex 2 is 4, forming a distorted tetrahedral configuration with 1,4-bis Azole methyl) benzene to take bidentate bridging coordination mode. Biomimetic catalytic bromination kinetics studies show that the above complexes show potential catalytic bromination activity.
