Triisopropyl borate → Butyldiisopropoxyborane

Participants

Reaction Steps

Following the method of Example 1, reaction of n-butyllithium (115 mL, 218 mmol) and triisopropoxyborane (41 g, 218 mmol) yielded n-butyldiisopropoxyborane, 37.3 g, (291 mmol, 93%). Proton NMR (neat) δ4.20 (septet, J=18 Hz, 2H), 1.23-0.63 (m, 9H) overlap with isopropyl doublet at 0.98 (d, J=18 Hz, 12H); boron NMR (neat) δ+30.2 ppm (s).
