Phosphonium, (2-ethoxy-1-methyl-2-oxoethyl)triphenyl-, bromide (1:1) Use and Manufacturing
The 1g of triphenylphosphine were dissolved in 15mL ethyl acetate was added 2-bromopropionate ethyl ester0.55mL2-, the reaction was stirred at room temperature 24h, and gradually a large amount of white solid was suction filtered, rinsed with ethyl acetate to give 1.35 g of a white solid, yield rate of 80.5percent.At 20-30°C, To a solution of triphenylphosphine (88 g) in toluene (the organic phase recovered in the first step of Example 3), an aqueous solution of potassium iodide (3 g) was added (the mother liquor from the first step of Example 3).Then alpha-bromo-propionic acid ethyl ester (60 g) is added, Reaction at 70-75 ° C for 15h;After the reaction is complete, Phase, Water cooling, Crystallization, Filtered to give the ethoxycarbonyl ethyl triphenylphosphonium bromide (144g);Organic phase recovery application, Aqueous mother liquor recovery application.
