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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
