In contrast to the wealth of information on organolithium
reagents,[1]
relatively little is known about the analogous
silyllithium compounds, despite their important role in silicon
chemistry.[2]
Furthermore, only a limited number of silyl metal
reagents have been characterized by X-ray crystallogra-
phy.[2, 3]
Of special interest are branched ªhypersilylº anions
