摘要： 在 NH4OAc 和 HOAc 的促进下, 使用环境友好的丙酮-水混合溶剂, 六齿八羟基喹啉锰类配合物 (Q3MnIII) 能够高效地催化 H2O2 氧化二甲亚砜 (DMSO). 卤素取代的 Q3MnIII 配合物具有更高的催化活性, 这归因于卤素取代基能加强 Q3MnIII 的畸变效应, 这一点经 B3LYP/6-311G+(d) 计算得到证实. 另外考察了一些因素对反应的影响, 并提出了一个催化反应机理.

Abstract: A series of hexadentate 8-quinolinolato manganese(III) complexes (Q3MnIII), with NH4OAc and HOAc as additives, were highly efficient catalysts for the oxidation of dimethylsulfoxide (DMSO) with aqueous hydrogen peroxide in an environmentally friendly acetone-water medium. The halogen substituents on the ligand improved the catalytic efficiency of Q3MnIII complexes, which was likely due to their strong distortion effect on Q3MnIII as indicated by the B3LYP/6-311G+(d) calculation. Various parameters were investigated and a reaction mechanism was proposed.

Key words: dimethylsulfoxide, catalytic oxidation, hexadentate 8-quinolinolato manganese(III) complex, hydrogen peroxide
