efficient approach for accessing unsymmetrical trisulfides through an I2-catalyzed three-component coupling of S-substituted sulphenylthiosulphates (RSSSO3Na), alkyl electrophiles and thiourea. This is the first report on utilizing RSSSO3Na as disulfurating reagent and provides a convenient method for converting bromides, chlorides, iodides and tosylates into trisulfides.
我们开发了一种通用且有效的方法,通过 I 2催化的S取代的磺基硫代硫酸盐 (RSSSO 3 Na)、烷基亲电子试剂和硫脲的三组分偶联来获取不对称三硫化物。这是第一篇利用RSSSO 3 Na作为二硫化试剂的报道,并提供了一种将溴化物、氯化物、碘化物和甲苯磺酸盐转化为三硫化物的便捷方法。
