摘要：

The 1-lithio-1-methyl-1-silafluorenide anion. (2) was prepared in high yield be reductive cleavage of the Si-Si bond from bis(1-methyl-1-silafluorenyl) (3) with lithium in THF at room temperature using ultrasonic waves. Treatment of 2 with trimethylchlorosilane produces 1-methy-1-(trimethylsilyl)-1-silafluorene NMR parameters (H-1, C-13, Si-29) of 2 are consistent with localization of charge on the silicon.
