9-Borabicyclo(3.3.1)nonane → 2-(4-Bromo-2,6-diethylphenyl)ethanol

Participants

Reaction Steps

Using a procedure analogous to that used to prepare 30B, 37B (1.2 g, 5 mmol) was heated in a pressure vessel with 9-BBN at 115° C. for 1 h to yield 37C (735 mg, 58%) as an orange oil. 1H NMR (400 MHz, CDCl3) δ ppm 1.21 (t, J=7.58 Hz, 6 H) 2.66 (q, J=7.49 Hz, 4 H) 2.92 (t, J=7.58 Hz, 2 H) 3.66-3.77 (t, J=7.57 Hz, 2 H) 7.17 (s, 2 H).
