Reaction Steps

Diethyl 10-(8-(benzyloxy)octyloxy)decylphosphonate (680 mg, 1.33 mmol) was dissolved in dry dichloromethane (15 mL). Bromotrimethylsilane (0.53 mL, 4.05 mmol) was added via syringe. The reaction was capped with a greased glass stopper and stirred overnight. The volatiles were removed under reduced pressure to yield a yellow oil. This was dissolved in 5:1 methanol:water (10 mL) and stirred 4 hours more. After concentration of the organic, the viscous yellow oil was recrystallized in acetonitrile to yield a white crystalline solid (590 mg, 98% yield). 1H NMR (400.14 MHz, DMSO) δ 7.40-7.19 (m, 5H), 4.42 (2H), 3.39 (t, J=6.48 Hz, 2H), 3.29 (t, J=6.46 Hz, 4H), 1.58-1.34 (m, 10H), 1.34-1.10 (m, 20H). 13C{1H} NMR (100.62 MHz, DMSO) δ 138.7, 128.2 (2C), 127.3 (2C), 127.3, 71.79, 69.91 (2C), 69.59, 30.11 (d, J=16.0 Hz), 29.25, 29.21, 29.20, 29.05, 28.89 (2C), 28.84 (2C), 28.73, 27.55 (d, J=136.5 Hz), 25.76, 25.69, 25.67, 22.74 (d, J=4.5 Hz). 31P{1H} NMR (161.97 MHz, DMSO): δ 27.74. Analysis calculated (found) %: C 65.76 (65.79), H 9.93 (10.00). MS (ESI, m/z): 455 (M−, 100%). Exact mass calculated (found) for [M−H]−, m/z): 455.2932 (455.2932).
