The oxidation of alkyl sulfides, sulfoxides, and sulfones was examined with either rabbit liver microsomes or a reconstituted system containing purified cytochrome P-450, S-dealkylation being found to take place more readily with alkyl sulfides bearing a higher acidic α-hydrogen. Similar results were obtained in the oxidation of alkyl sulfides by hydroxyl radical. Both S-dealkylation and S-oxygenation products are presumed to be formed via the cation radical intermediate.
用兔肝脏微粒体或含有纯化细胞色素 P-450 的重组系统对烷基硫化物、硫醚和砜的氧化进行了研究,发现带有酸性较强的 α-氢的烷基硫化物更容易发生 S-脱烷基化反应。羟自由基氧化烷基硫化物时也得到了类似的结果。据推测,S-脱烷基化和 S-氧化产物都是通过阳离子自由基中间体形成的。
