The general procedure for the synthesis of (methoxymethyl)triphenylphosphonium chloride from chloromethyl methyl ether and triphenylphosphine was as follows: 20.0 g of triphenylphosphine was placed in a round-bottomed flask, dissolved in an appropriate amount of toluene, and heated to 95°C. The reaction was carried out at a constant temperature for 16 hours. Subsequently, 6.37 mL of chloromethyl methyl ether was slowly added dropwise and the reaction was kept at temperature for 16 hours. Upon completion of the reaction, the reaction mixture was cooled to room temperature and the solid product was collected by filtration. The filter cake was washed three times with toluene to remove impurities and then dried to give 25.4 g of white phosphonium salt in 97.3% yield.
