dithionite, sodium thiosulfate and rongalite promoted one-pot synthesis of aryl alkyl sulfides at room temperature has been developed. The reactions of a range of disulfides with alkyl halides proceeded smoothly in the presence of rongalite. Possible reaction pathways are discussed and the effects of these sulfites on disulfides are investigated. The important features of this protocol are metal-free, strong-base-free
开发了一种连二亚硫酸钠、硫代硫酸钠和雕白粉在室温下促进芳基烷基硫醚的一锅法合成。一系列二硫化物与卤代烷的反应在雕白粉的存在下顺利进行。讨论了可能的反应途径,并研究了这些亚硫酸盐对二硫化物的影响。该协议的重要特点是无金属、无强碱、反应条件温和、操作简单、反应时间短、产品收率高。
