Procedure

Cyclopentyldiisopropoxyborane (2.33 g, 37 mmol) in ethyl ether (37 mL) was added to an ethereal solution of 1octynyllithium (41 mmoL in 41 mL ethyl ether), then quenched with HCl in ethyl ether (12.0 mL, 41 mmol). Workup as described in Example 14 yielded 6.95 g (76%), bp 100°-102° C. (0.1 mm Hg); n20D 1.4557; proton NMR (CDCl3) δ4.63 (septet, J=18 Hz, 1H), 2.23 (triplet, 1H), 1.17 (d, J=18 HZ, 6H), 0.83 (triplet, 3H); boron NMR (EE) δ+41.2 ppm(s); mass spectrum (chemical ionization, isobutene) m/e 249 (M+H), 40%); IR (thin film) 2186, 1344 cm-1. Calcd. for C16H29BO: C, 77.42; H, 11.78. Found: C, 77.02; H, 11.92.
