1. A general method for the preparation of symmetrical and unsymmetrical disulfonyl sulfides was established starting from sodium alkanethiosulfonates and alkanesulfonyl chlorides. 2. Thiosulfonates and disulfonyl sulfides were found to be reduced to the corresponding disulfides and trisulfides respectively. These results suggest that the unsymmetrical disulfides and trisulfides might be prepared generally by this method. 3. Trisulfides were found to be desulfurizated to the corresponding sulfides via disulfides. 4. Oxidation of alkylaryldisulfides occurred preferentially on the farthest sulfur atom from the electron releasing alkyl group.
1. 建立了一种从烷基硫酸钠和烷基磺酰氯出发制备对称和不对称二磺酰硫化物的一般方法。
2. 发现硫酸酯和二磺酰硫化物可分别被还原为相应的二硫化物和三硫化物。这些结果表明,不对称的二硫化物和三硫化物可能通过该方法普遍制备。
3. 三硫化物可以通过二硫化物被脱硫还原为相应的硫化物。
4. 烷基芳基二硫化物的氧化 preferentially发生在距离电子释放的烷基团最远的硫原子上。
