Palladium-catalysed addition of tin-tin and tin-silicon bonds to allenes

Article abstract of DOI:10.1016/0022-328X(91)86310-M

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.
