Related Products of 191014-55-8, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 191014-55-8, name is 4-Fluoro-2-methoxybenzonitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
To 4-fluoro-2-methoxybenzonitrile (3.00 g, 20 mmol) and N-iodosuccinimide (NIS) (4.7 g, 21 mmol) under nitrogen was added TFA (35 mL) and the reaction was stirred at room temperature for 20 hours. The volatiles were removed in vacuo and the residue was taken up in 1:1 ethyl acetate:ether and was washed with aqueous sodium bicarbonate and then brine containing enough sodium sulfite to remove the iodine color. The aqueous layers were back extracted with more 1:1 ethyl acetate:ether and the combined organic layers were dried over sodium sulfate and evaporated. The residue was treated with ether/hexanes to afford clean iodo title product as a white solid. 1H-NMR (500 MHz, CDCl3) delta ppm 3.930 (s, 3H), 6.730 (d, J = 9.4 Hz, 1H), 7.900 (d, J = 6.8 Hz, 1H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Fluoro-2-methoxybenzonitrile, other downstream synthetic routes, hurry up and to see.
