A novel synthetic strategy to silyl-protected terminal alkynyl sulfides via reaction of lithium 2,2,2-tris(trimethylsilyl)ethanedithioate, produced by the reaction of tris(trimethylsilyl)methyllithium with carbon disulfide, and alkyl or benzyl halides has been developed. The scope of the reaction is broad, with a variety of benzylic and aliphatic halides and products were formed in good to excellent
通过三(三甲基甲硅烷基)甲基锂与二硫化碳的反应生成的2,2,2-三(三甲基甲硅烷基)乙烷二硫酸锂反应,开发了一种甲硅烷基保护的末端炔基硫醚的新型合成策略。反应的范围很广,有各种苄基和脂肪族卤化物,生成的产物的收率好至极好。
