Procedure
To a solution of triphenylphosphine (1.31 g, 5.01 mmol) in toluene (6.5 mL) was added 2,6-diethoxybenzyl bromide (1.3 g, 5.01 mmol) and the mixture stirred at room temperature overnight. Diethyl ether was added and the solid was collected by filtration to give (2,6-diethoxybenzyl)triphenylphosphonium bromide as an off-white solid. Yield (1.58 g, 60%): 1H NMR (400 MHz, DMSO-d6) δ 7.83-7.87 (m, 3H), 7.68 (ddd, J=7.6, 7.6, 3.2 Hz, 6H), 7.55 (d, J=7.6 Hz, 3H), 7.52 (d, J=7.2 Hz, 3H), 7.18 (ddd, J=8.4, 8.4, 2.4 Hz, 1H), 6.45 (d, J=8.4 Hz, 2H), 4.66 (d, J=14.0 Hz, 2H), 3.65 (q, J=6.8 Hz, 4H), 1.01 (t, J=6.8 Hz, 6H).
