Participants

Reaction Steps

To a solution of triphenylphosphine (45.24 g, 0.12 mol) in 200 mL of ether was added 3-fluorobenzyl bromide (22.7 g, 0.12 mol). The resulting solution was allowed to stir at rt overnight. The white solid was collected by filtration and dried to give 58.0 g (85%) of the product as a white solid. mp 290-292° C. 1H NMR (CHCl3) 5.516 (d, J=14.7 Hz, 2 H), 6.725 (d, J=9.6 Hz, 1 H), 6.893 (m, 2 H), 7.084 (m, 2 H), 7.622-7.762 (m, 15 H).
