Into a one-liter 3-necked flask equipped with stirrer, condenser, addition funnel, and thermometer there was charged 500 ml xylene and 100 g. triphenylphosphine. There was slowly added 77 grams of 1,3-dibromopropane to the stirred solution at 130° C. After heating for 20 hours at 130° C., the resulting suspension was cooled and filtered to give 131.2 g of (3-bromopropyl)triphenylphosphonium bromide (M.P. 229°-30° C.).
