For organometallicsulphides p-Me3XC6H4SMe (I), p-Me3XCH2C6H4 SMe (II), and PhSCH2XMe3(III)(X = Si, Ge. Sn, or Pb) the oxidation rates with perbenzoic acid have been measured spectrophotometrically at 25° and compared with the ionization energies obtained by u.v. photoelectron spectroscopy measurements. From the results obtained for sulphides (I), +I, (p→d)π and hyperconjugative contributions almost
对于有机金属硫化物p -Me 3 XC 6 H 4 SMe(I),p -Me 3 XCH 2 C 6 H 4 SMe(II)和PhSCH 2 XMe 3(III)(X = Si,Ge.Sn或Pb )已在25°分光光度法测量了过苯甲酸的氧化速率,并将其与通过uv光电子能谱测量获得的电离能进行了比较。从硫化物(I)+ I,(p → d)π的结果超共轭作用几乎抵消了;对于系列(II)和(III),CH 2 XMe 3基团的电子释放特征证实了C-金属超共轭的重要性。还研究了溶剂对标题化合物氧化速率的影响,并进行了详细讨论。

Sulfides are oxidized to sulfoxides by stoichiometric amounts of perfluoro-cis-2,3-dialkyloxaziridines 2. The reactions proceed at -40 degrees C with nearly complete selectivity and very good yields. Sulfoxides are also oxidized easily by 2 under mild conditions to corresponding sulfones. The oxidation of some bioactive sulfides (promazine, albendazole, biotin, and others) is also reported.
