Methyl 2-chloro-4-vinylbenzoate → Methyl 2-chloro-4-ethylbenzoate

Participants

Reaction Steps

Charged methyl 2-chloro-4-ethenylbenzoate (437 mg, 2.23 mmol), BaSO4/Pd (100 mg, 5%) and ethyl acetate (9 mL) to a flask, the mixture was then purged with H2, and stirred at room temperature for 4 h. The reaction mixture was then filtered, concentrated to give 424 mg of the title compound (96%). 1H NMR (400 MHz, CDCl3): δ 1.24 (3H, t, J=7.6 Hz), 2.65 (2H, q, J=7.6 Hz), 3.91 (3H, s), 7.12 (1H, dd, J=1.2 Hz, 8.4 Hz), 7.28 (1H, d, J=1.6 Hz), 7.77 (1H, d, J=8.0 Hz).
