Reaction Steps

To a solution of 2-ethyl-6-methylbenzylbromide (0.432 g, 2.03 mmol) in toluene (10 mL) was added triphenylphosphine (0.6018 g, 2.29 mmol). The mixture was heated at 100° C. for 4 h. After cooling to room temperature, the precipitate was collected by filtration and washed with toluene to give 2-ethyl-6-methylbenzylphosphonium bromide as a solid. Yield (0.958 g, 99%). 1H NMR (400 MHz, DMSO-d6) δ 7.90-7.92 (m, 3H), 7.69 (ddd, J=8.4, 8.4, 3.6 Hz, 6H), 7.49-7.55 (m, 6H), 7.20 (ddd, J=7.6, 7.6, 2.8 Hz, 1H), 7.02 (d, J=8.0 Hz, 1H), 6.94 (d, J=7.6 Hz, 1H), 4.91 (d, J=14.7 Hz, 2H), 2.05 (q, J=6.7 Hz, 2H), 1.75 (s, 3H), 0.78 (t, J=6.7 Hz, 3H).
