Reaction Steps

66.5 g (0.298 mol) of 2-(3-bromopropyloxy)tetrahydropyran is refluxed together with 82 g (0.312 mol) of triphenylphosphine and 1 g of tetrabutylammonium iodide in 500 ml of acetonitrile for 24 hours. After evaporation of the solvent, the residue is triturated several times with boiling diethylether. 144 g (100%) of 3-(tetrahydropyranyloxy)propyl-triphenylphosphonium bromide is obtained as heavy oil. (C26H30BrNO2P; F.W. 485.4).
