  The mechanism for the oxidation of sulfides by [(me₄-salen)Cr^V(O)(pyO)]CF₃SO₃, where me₄-salen is 8,8,8',8'-tetramethylsalen and pyO is pyridine N-oxide, has been investigated. Results from Hammett correlations on the rates of oxidation of substituted thioanisoles, frontier molecular orbital calculations, and product studies are consistent with a mechanism that is initiated by a single electron transfer to give a radical cation intermediate.Key words: oxidation, chromium(V), sulfides, radical cation, oxygen transfer.

  研究了[(me4-salen)CrV(O)(pyO)]CF3SO3（其中me4-salen是8,8,8'，8'-四甲基萨伦，pyO是吡啶N-氧化物）氧化硫化物的机理。通过对取代硫代苯甲醚氧化速率的Hammett相关性、前线分子轨道计算和产物研究的结果表明，该机理的起始步骤是通过单电子转移产生自由基阳离子中间体。关键词：氧化，铬（V），硫化物，自由基阳离子，氧转移。
