Procedure
n-Hexyl(3,3-dimethyl-1-butynyl)isopropoxyborane was prepared by adding 2-n-hexyl-diisopropoxyborane (8.35 g, 39 mmol) in ethyl ether (18 mL) to an ethyl ether solution of 3,3-dimethyl-1-butynyllithium (44 mmol in 44 mL of ethyl ether), following the method of Example 14, and quenched with HCl in ethyl ether (12.87 mL, 44 mmol). Yield: 7.2 g (79%), bp 80°-82° C. (0.1 mm Hg); n20D 1.4265, boron NMR (ethyl ether) δ+40.6 ppm(s); mass spectrum (chemical ionization, isobutene) m/e 237 (M+H, 7%); IR (thin film) 2186, 1327 cm-1. Anal. Calcd. for C15H29BO: C, 76.23; H, 12.38; B, 4.58. Found: C, 76.35; H, 12.02; B, 4.61.
