| 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,这归因于卤索取代基能加强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 (Q_3Mn~III), with NH4OAc and HO Ac 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 Q_3Mn~III complexes, which was likely due to their strong distortion effect on Q_3Mn~III as indicated by the B3LYP/6-311 G+(d) calculation. Various parameters were investigated and a reaction mechanism was proposed. |
