실험 절차

The title compound was prepared following the method of Example 14, using 1-hexynyllithium (64 mmol) prepared from 1-hexyne and n-butyl lithium in ethyl ether (64 mL) and phenyldiisopropoxyborane (11.96 g, 58 mmol) dissolved in ethyl ether (60 mL) and quenched with hydrogen chloride in ethyl ether (18.7 mL, 64 mmol). Yield. 11.2 g (86%), bp 102°-105° C. (0.4 mm Hg); n20D 1.5008; proton NMR (CDCl3) δ7.90 (m, 2H), 7.31 (m, 3H), 4.87 (septet, J=18 Hz, 1H), 2.33 (triplet, J=18 Hz, 2H), 1.23 (d, J=18 Hz, 6H), 0.90 (triplet, 3H); boron NMR (CDCl3) δ+36.5 ppm(s); mass spectrum (chemical ionization, isobutene) m/e 229 (M+H, 10%); IR (thin film) 2195, 1324 cm-1.
