実験手順
A solution of 1-(4-bromobutoxy)-4-fluorobenzene (2.56 g) and triphenylphosphine (2.72 g) in toluene (10 mL) was heated under reflux for 24 hours. The reaction mixture was allowed to cool to room temperature, and the precipitated solid was collected by filtration and dried to obtain [4-(4-fluorophenoxy]butyl]triphenylphosphonium bromide (2.06 g).
