Sodium Iodide → 2,4-Dibromo-6-methylphenyl 2-methylprop-2-en-1-yl ether

Participants

Reaction Steps

A solution of 2,4-dibromo-6-methyl-phenol (Compound 3,62 g, 0.23 mol) in 700 mL of acetone was treated with potassium carbonate (38.7 g, 0.28 mol), sodium iodide (3.4 g, 0.023 mol) and 3-chloro-2-methylpropene (34 mL, 0.35 mol) and the resulting suspension was refluxed for 18 hours. The solids were filtered and the filtrate was evaporated in vacuo to afford the title compound as a dark yellow oil. 1H-NMR (300 MHz, CDCl3): δ 7.53(d, 1H, J=2.7 Hz), 7.27(d, 1H, J=1.9 Hz), 5.17(s, 1H), 5.02(s, 1H), 4.28(s, 2H), 2.30(s, 3H), 1.92(s, 3H).
