Procedure
In 175 ml of dimethylformamide were dissolved 1,513 g of p-xylylene dichloride and 50 g of triphenylphosphine and they were reacted for 3 hours under refluxing. Thereafter, the reaction mixture was cooled to room temperature, washed twice with each 100 ml of dimethylformamide and then washed twice with each 100 ml of diethyl ether, and then dried under reduced pressure to provide white powdery p-xylylenebis(triphenylphosphonium chloride) (XTPPC) having the following structure at a yield of 90%. ##STR13##
