A solution of 3-fluorobenzyl bromide (4.73 g) in dry toluene (5.0 cm3) was added to a stirred suspension of triphenylphosphine (4.87 g) in dry toluene (5.0 cm3) and after 30 minutes the resultant precipitate was collected by filtration and washed with toluene to yield 4-fluorobenzyltriphenylphosphonium bromide (7.1 g) as a white solid.
