| Abstract: | Methylthio- and methylsulfonyl thiophenes were polymetallated by n-buthyllithium and superbase (LICKOR) in one-step. 2-(Methylthio)thiophene was bimetallated in 5 and in alpha to the methylthio sulfur atom by superbase. 3-(Methylthio)thiophene was bimetallated in both 2 and 5 positions by the organolithium and trimetallated in these two positions and in alpha to the thioethereal sulfur atom by superbase. 3-(Methylsulfonyl)thiophene was bimetallated in 2 and in alpha to the sulfonyl sulfur atom by the organolithium while the 2-(methylsulfonyl)thiophene underwent degradation in the same conditions. |
