We present here the results on the use of 1-n-butyl-3-methylimidazolium methylselenite, [bmim]
[SeO2(OCH3)], in the synthesis of symmetrical disulfides starting from thiols. 这里展示了我们使用1-n-butyl-3-methylimidazolium methylselenite ,由硫醇合成对称性二硫化物的结果。This efficient and improved method is general for aromatic, aliphatic, and functionalized thiols affording the disulfides in good to excellent yields after easy work up. 这一有效和改进的方法对芳香族、脂肪族和功能化硫醇都是适用的,稍作整理即可以良好的收率生成二硫化物。The use of a microwave accelerates the reaction and the [bmim] [SeO2(OCH3)] was reused for further oxidation reactions.微波的使用提高了反应速度,[bmim] [SeO2(OCH3)]在进一步的氧化反应中得到重复利用。 |
