Triphenylphosphine → [(3-Bromophenyl)methyl](triphenyl)phosphanium bromide

Participants

Reaction Steps

A stirred mixture of 3-bromobenzyl bromide (Aldrich) (5.1 g, 20.5 mmoles), triphenylphosphine (54 g, 0.20 moles), and CH3CN (100 mL) was refluxed for 20 hours. The cooled reaction mixture was then concentrated and the residue triturated with hexanes (10×) to remove excess triphenylphosphine. The remaining white solid was collected by filtration and then dried in vacuo to give 11-2 as a white solid.
