A magnetically stirred suspension of 1-bromononane (Aldrich, 40 g, 0.1931M) and triphenylphosphine (101.3 g, 0.3862 mole) was heated at 100° C. (oil bath) for 2 hours. The resulting homogeneous solution was then cooled and triturated with ether (8X) to remove most of the unreacted triphenylphosphine. A viscous gum was obtained which was dissolved in CH2Cl2 and concentrated in vacuo to give the title phosphonium salt as a light yellow, extremely hygroscopic foam weighing 85 g (80.1%). TLC, neat CH2Cl2, Rf =0.78, PMA.
