Sodium Acetate → 3,5-Difluorotoluene

Participants

Reaction Steps

A mixture of 1-(bromomethyl)-3,5-difluorobenzene (50 g, 0.24 mol), 10% Pd/C (3 g) and sodium acetate (140 g, 1.7 mol) in anhydrous ether (250 mL) was stirred under hydrogen at atmospheric pressure for 24 hr. The mixture was filtered and the filtrate was dried over anhydrous Na2SO4, filtered and used directly in the next step. 1H-NMR (500 MHz, CDCl3): δ 6.56 (d, 2H, J=6.0 Hz), 6.47 (t, 1H, J=9.0 Hz), 2.22 (s, 3H).
