Nonsolvated, Aggregated 1,1-Dilithiosilane and
the Derived Silyl Radicals**

Dedicated to Professor Josef Michl
on the occasion of his 65th birthday
The chemistry of the potentially synthetically versatile
geminal 1,1-dilithiosilyl compounds [R2SiLi2] is still in its
infancy, in contrast to the chemistry of monosilyllithium
compounds [R3SiLi], which have been studied intensively.[1]
Several [R2SiLi2] compounds have been reported,[2,3]
although only a few of them have been isolated and
characterized by X-ray crystallography (all in solvated
form).[2e,f,3c]
The aggregation behavior and the structures of
dilithiosilanes in weakly solvating media are unknown. Only
limited structural information is also available for geminal
