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

Hexamethyl-, hexaethyl- and hexabutyl-ditin add to a variety of allenes in the presence of Pd(PPh3)4; the reaction is reversible. Trimethylsilyltrimethyl- and -tributyl-stannane also add under comparable conditions, the silyl moiety becoming attached to the central carbon atom of the allene skeleton; this reaction is, however, apparently not reversible.
