(Methoxymethyl)triphenylphosphonium chloride Use and Manufacturing
20 g of triphenylphosphine was placed in a round bottom flask, dissolved in toluene, heated to 95 ° C, and 6.37 mL of chloromethyl methyl ether was added, and the reaction was carried out for 16 hours. After the reaction is complete, Cool to room temperature, filter, filter cake washed with toluene three times, dry, Obtained 25.4 g of white phosphonium salt, yield 97.3percentUnder nitrogen, 50 mL of anhydrous acetone was added to the reactor, Then 32 g of triphenylphosphine was added, While stirring, the temperature was raised to 37 ° C, While maintaining the temperature, 20 g of methyl chloromethyl ether was added to the reactor, Followed by reaction at 37 ° C for 3 h, The temperature was gradually raised to 47 ° C at a rate of 1 ° C / min and the reaction was continued for 3 h, The reaction was stopped, filtered, washed with anhydrous ether, dried, To give 37.0 g (methoxymethyl) triphenylphosphonium chloride in a yield of 88.5percent.
