Abstract

Tetrakis(di-tert-butylmethylsilyl)disilene (3) was treated with 2 equiv. of metal naphthalenide (M = Li, Na, and K) in THF to give the disilenyl anion by elimination of one ^tBu ₂MeSi group, through the intermediate formation of a disilene dianion upon two-electron reduction. The red crystals of sp ²-type silyl anions were isolated as the corresponding alkali metal derivatives, which were characterized by NMR spectra and X-ray crystallography.
