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.

The addition reaction of silylstannanes with allenes in the presence of Pd2(dba)3·dba in toluene affords (E)-alkenylsilanes having an allylstannane moiety exclusively in good to excellent yields.
