실험 절차

The same procedure for 8-nonyn-1-ol was followed with 9-dodecyn-1-ol (4.68 g, 25.7 mmol), KH(3.09 g, 77.0 mmol), and 1,3-diaminopropane (70 mL). This produced 4.33 g of yellow oil (93%): IR (neat) ν 3317,2930, 2121 cm−1; 1H—NMR δ 3.62 (t, 2H, J=6.6 Hz), 2.17 (td, 2H, J=2.6 Hz, 7.1 Hz), 1.93 (t, 1H, J=2.6 Hz), 1.76 (bs, 1H), 1.55 (m, 4H), 1.28 bm, 12H); 13C—NMR δ 84.8, 68.0, 63.0, 32.7, 29.5, 29.4 (2C), 29.0, 28.7, 28.4, 25.7, 18.4; MS m/z 189.18 (M++Li).
