Carbanions produced by deprotonation at the ring C-4 of 2,2-disubstituted 1,3-dithianes undergo a Wittig type rearrangement to give the anions of 2,2-disubstituted tetrahydrothiophene-3-thiols. After being trapped with several alkyl halides, these afford the corresponding 2,2-disubstituted 3-(alkylthio)tetrahydrothiophenes, which are difficult to prepare by other synthetic routes.
在 2,2-二取代的 1,3-二噻烷的 C-4 环上通过去质子化产生的碳负离子经历 Wittig 型重排,得到 2,2-二取代的四氢噻吩-3-硫醇的阴离子。在被几种烷基卤化物捕获后,它们得到相应的 2,2-二取代 3-(烷硫基)四氢噻吩,这是其他合成路线难以制备的。
