(4-Carboxybutyl)triphenylphosphonium bromide Use and Manufacturing
General procedure: A mixture of ω-bromocarboxylic acid (1 equiv) and triphenylphosphine (1 equiv) in 300 mL of toluene was refluxed for 48 h under argon. The mixture was allowed to cool at room temperature and concentrated in vacuum. The residue was crystallized from various solvents to give the corresponding phosphonium salt.5-bromopentanoic acid (5.01 g, 0.03 mol) and triphenylphosphine (2.62 g, 0.01 mol) were added to a 100 mL flask, 50 mL of acetonitrile was added and the mixture was heated to 80 ° C for 48 hours. After the reaction was completed, the solvent was spin dried. The reaction system was introduced into cyclohexane to collect precipitated oily precipitate and vacuum-dried product in a yield of 50percent.
