実験手順
To a solution of 1-bromo-4-fluoro-2-(prop-1-en-2-yl)benzene (200 mg, 0.930 mmol) in DCM (5 mL) was added 5% Rhodium on Alumina (30 mg, 0.015 mmol). The resulting mixture was stirred under hydrogen atmosphere (50 psi) for 18 h after which time the reaction was filtered through Celite™ and concentrated in vacuo to afford 1-bromo-4-fluoro-2-isopropylbenzene. 1H NMR (400 MHz, CD2Cl2) δ ppm 7.48 (dd, J=8.6, 5.7 Hz, 1H), 7.01 (dd. J=10.3, 3.1 Hz, 1H), 6.82-6.75 (m, 1H), 3.38-3.25 (m, 1H), 1.21 (d, J=6.9 Hz, 6H).
