Allyltri-n-butyltin acts as an allylation reagent for aldehydes catalyzed by chiral Lewis acids and ytterbium(III) trifluoromethanesulfonate. It is also used to prepare homoallylic alcohols with trichloro-1,3,5-triazene. Further, it plays an important role for tetrakis(triphenylphosphine)palladium(0) catalyzed coupling reaction with iodoquinones and allyl acetates.
Widely used nucleophilic, non-basic allylating agent.

Lewis acid-catalyzed stereoselective addition to aldehydes gives homoallylic alcohols: Chem. Lett., 919 (1979); Tetrahedron Lett., 25, 265, 1879 (1984); Synlett, 1694 (2002). For chemoselective allylation of aldehydes in the presence of ketones, see: Tetrahedron Lett., 36, 3723 (1995). In the presence of TI(O-i-Pr)4 and BINOL, enantioselective allylation of ketones can be accomplished with high ee: Tetrahedron: Asym., 11, 4163 (2000).
Similarly, homoallylamines are formed from aldimines with TiCl4 or BF3 etherate: J. Org. Chem., 50, 146 (1985). For allylation of quinones, see p-Benzoquinone, A13162.
