Versuchsvorschrift

340 g (1.93 mol) of 1-chloromethylnaphthalene (Aldrich) are dissolved together with 505.7 g (1.93 mol) of triphenylphosphine in 2 l of acetonitrile. The mixture is subsequently boiled at reflux with stirring for 5 hours. The phosphonium chloride begins to precipitate out after about 2 hours. The mixture is left to cool at room temperature and the crystals are filtered off with suction.
