Abstract
Three different types of silacyclopentadienyl anions have been obtaine d in the reduction of 1-methylsilole 1 with excess lithium. Treatment of lithiated solution with dimethylchlorosilane gave 2,5-bis(dimethyls ilyl)silole derivatives 3a and 3b, and with trimethylchlorosilane gave 1-trimethylsilyl-1-methylsilole derivative 4 at an early stage, and 1 ,1-bis(triemthylsilyl)silole derivative 8 at a late stage. Silole 1,1- dianion 7 has been formed via silole 2,5-dianion 2 and silole 1-anion 5.
