Versuchsvorschrift
The 3-phthalimidopropyltriphenylphosphonium bromide was prepared as follows. To a solution of triphenylphosphine (24.5 g, Aldrich, U.S.A.) in toluene (200 mL) was added N-(3-bromopropyl)phthalimide (25 g, Aldrich, U.S.A.). The mixture was heated to reflux overnight. The white solid so formed was isolated by filtration and dried under vacuum to yield 3-phthalimidopropyltriphenylphosphonium bromide (22.8 g).
