実験手順

PhLi (0.56 mL, 1.8M in di-n-butyl ether, 1 mmol) was added to a stirred solution of 8-diphenylphoshinoquinoline (1) (156 mg, 0.5 mmol) in dry THF (5 mL) at −78° C. and the solution was stirred at 0° C. for 10 minutes. The solution was then cooled to −78° C., saturated aqueous NH4Cl solution (10 mL) was added and the mixture was warmed to room temperature. Products were extracted with EtOAc, washed with water and saturated aqueous NaCl, dried (MgSO4) and evaporated to give 4 (196 mg) quantitatively as a yellow oil. 1H NMR (400.13 MHz, CDCl3) δ 7.4-7.3 (m, 15H, Ph-H), 6.92 (d, 1H, J=7.2 Hz, C5—H), 6.69 (ddd, 1H, J=7.2, 6.0, 1.2 Hz, C7—H), 6.54 (t, 1H, J=7.2 Hz, C6—H), 6.38 (d, 1H, J=9.6 Hz, C4—H), 5.64 (dd, 1H, J=10.0, 4.0 Hz, C3—H), 5.44 (bs, 1H, N1—H), 5.15 (d, 1H, J=7.2 Hz, C2—H) ppm; 13C NMR (100.61 MHz, CDCl3) δ 146.5 (d, J=19.2 Hz), 145.1, 135.4 (d, J=8.1 Hz), 135.3 (d, J=7.1 Hz), 134.5, 133.7 (d, J=18.2 Hz), 133.6 (d, J=19.2 Hz), 133.4 (d, J=19.2 Hz), 127.3, 128.7-128.3 (m), 127.1, 126.0, 125.2, 124.5, 119.1, 117.1, 116.1 (d, J=8.1 Hz), 57.6 ppm; 31P NMR (161.97 MHz, CDCl3) δ −23.8 ppm.
