A monolithiated and its related 1,3-dilithiated allylsilane: syntheses, crystal structures, and reactivity.
Treatment of Me2Si(CH2CH=CH2)(CH2NC5H10) with 1 or 2 equiv of t-BuLi afforded the mono- or dilithiated allylsilanes, which crystallize as a tetramer and a hexamer from pentane. The product selectivity in trapping reactions is influenced by the ability of both the solvent and the electrophile to coordinate the lithium center.
