bidentate sulfenamide coordination through the sulfur and oxygen atoms favors the S-arylation pathway. The mild and environmentally benign catalytic conditions enable broad functional group compatibility, allowing a variety of diaryl or alkyl aryl sulfilimines to be efficiently prepared. The Chan–Lam coupling procedure could also tolerate alkenylboronic acids as coupling partners to afford alkenyl aryl

efficient approach for accessing unsymmetrical trisulfides through an I2-catalyzed three-componentcoupling 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。
