Tris(trimethylsilyl)silyllithium (3) reacted with aldehydes and ketones (molar ratio 2 : 1) according to a modified Peterson mechanism under formation of transient silenes, which were immediately trapped by excess 3 to give the organolithium derivatives (Me 3 Si) 3 SiSi(SiMe 3 ) 2 C(Li) Ε”1 R 2 (7).
