Free radical and palladium-catalysed hydrostannation of allenes: a comparison
Mitchell, Terence N.,Schneider, Ulrich

While free radical hydrostannation of monosubstituted allenes with Me3SnH affords mixtures of varying composition, cyclohexylidene allene is attacked by the stannyl radical preferentially at the central carbon atom.In contrast, palladium-catalysed hydrostannation involves a regioselective attachment of the organotin moiety to the less highly substituted terminal carbon atom of the allene framework.
FORMATION OF α-SILYLVINYLLITHIUM REAGENTS: REACTIONS OF α-SILYL- AND α-STANNYL-VINYLLITHIUMS WITH ALDEHYDES AND KETONES
Mitchell, Terence N.,Reimann, Werner

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.
