FORMATION OF α-SILYLVINYLLITHIUM REAGENTS: REACTIONS OF α-SILYL- AND α-STANNYL-VINYLLITHIUMS WITH ALDEHYDES AND KETONES

The formation of α-trimethylsilylvinyllithium compounds from 1-trimethylsilyl-1-trimethylstannyl-1-alkenes have been studied and their stabilities investigated. α-Trimethylsilyl- and α-trimethylstannyl-vinyllithiums undergo 1,2-addition to aldehydes and non-enolisable ketones, to give silyl- or stannyl-substituted allylic alcohols; α,β-unsaturated ketones, however, undergo 1,4-addition to give homoallylic ketones.
α-METALLATED VINYL CARBANIONOIDS. I. FORMATION OF α-STANNYLVINYL ANIONOIDS FROM 1,1-BIS(TRIMETHYLSTANNYL)ALKENES
Mitchell, T.N.,Amamria, A.
, p. 47 - 56 (2007/10/02)
Hydrostannation of 1-stannyl-1-alkynes leads to the formation of 1,1- and 1,2-distannyl-1-alkenes.The former can undergo lithiation (by alkyllithium in THF) with varying degrees of stereospecificity. 1,1-Dilithio-1-alkenes cannot be prepared by double lit
