Lithium 1,1-diadamantylamide (LDAM) base-promoted insertion of arynes into disulfide S–S bonds is described. After generation of arynes from readily available aryl halides and triflates, reactions with diaryl and diisopropyl disulfides afford the insertion products in moderate to excellent yields. Use of 1-cyclohexenyl triflate gave an excellent yield of 1,2-bis(phenylthio)cyclohexene.
描述了1,1-二金刚酰胺锂(LDAM)碱促进的芳烃插入二硫键的S–S键。从易于得到的芳基卤化物和三氟甲磺酸酯生成芳烃后,与二芳基和二异丙基二硫化物的反应可中等至极好地获得插入产物。使用1-环己烯基三氟甲磺酸酯具有极好的1,2-双(苯硫基)环己烯收率。
