【摘要】 近年来,大环配体合成的金属配合物具有很好的催化活性及生物活性因此一直备受关注。[1]而模板合成方法在合成大环配体中被广泛的使用。[2]我们以金属镍离子为模板,以5,5-二氨基-1H,1H-3,3’-双-1,2,4-三氮唑(DABT)为原料通过溶剂热法合成18元大环金属配合物。该环中有8个氮原子,其中有四个氮原子与金属离子配位,该配合物具有较好的平面性。利用该配合物催化甲基苯基硫醚不对称氧化,获得了e.e值为30.6%的甲基苯基亚砜。催化甲基苯基硫醚不对称氧化性质正在进一步研究当中。更多还原

【Abstract】 In recent years,the design and synthesis of macrocyclic ligands have attracted increasing attention in fields such as bioinorganic chemistry,catalysis properties.Template synthesis has been widely studied as a synthetic route for macrocyclic ligands.In this paper,new square-planar Ni(II) complex of 18-membered octoaza macrocyclic ligands has been synthesized and characterized.The nickel(II) complex has square-planar coordination geometry and contains eight nitrogen atoms.And Ni(II) is coordinated by four nitrogen atoms from macrocyclic ligands and two chlorine atoms.The catalytic oxidation of methyl phenyl sulfide property of complex has been investigated,the methyl phenyl sulfoxide was obtained in 30.6% e.e.更多还原
