Adding a certain compound to certain chemical reactions, such as: 5458-84-4, name is 1-Iodo-2-methoxy-4-nitrobenzene, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 5458-84-4, Quality Control of 1-Iodo-2-methoxy-4-nitrobenzene
A mixture of Cu l (6.80 g, 35.84 mmol ), CsF ( 14. 15 g, 93.18 mmol ) l -iodo-2-methoxy- 4-nitrobenzene ( 10 g, 35.84 mmol ) and sulfolane (20 ml ), was stirred rapidly at 45 C. To this mixture was added trimethyl(trifluoromethyl)silane ( 13.25 g, 93. 1 mmol ) dropwise over 4 hours using a syringe pump, and the resulting mixture was stirred at 45C for 1 8 hours. The mixture was diluted with ethyl acetate (500 mL ) and stirred with Celite for 5 min. The reaction mixture was filtered through a pad of Celite, diluted with ethyl acetate ( 500 mL ). The organic layer was washed with 10% NH4OH, 1.0 N HCl, brine, dried over Na2SC>4, filtered, and concentrated to give the crude product.The crude product was purified by chromatography (ethyl acetate/petroleum ether 0/1 to 1/4) to give intermediate 444 (8 g, 91% yield ) as a white solid.
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, 1-Iodo-2-methoxy-4-nitrobenzene, other downstream synthetic routes, hurry up and to see.
