Reference of 202865-85-8, 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. 202865-85-8, name is 1-Bromo-4-iodo-2-methylbenzene belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
A mixture of 10H-spiro[acridine-9,9?-fluorene] (1) (4.50 g,13.60 mmol), 1-bromo-4-iodo-2-methylbenzene (4.45 g, 15 mmol),copper iodide (260 mg, 0.1.36 mmol), (¡À)-trans-1,2-diaminocyclohexane(0.34 mL, 2.8 mmol) and sodium tert-butoxide (2.60 g,2.80 mmol) in 1,4-dioxane (15 mL) was refluxed overnight under a nitrogenatmosphere. The reaction mixture was then filtered through apad of silica and extracted with chlorofrom. The organic layer waswashed with water and brine, and dried over anhydrous sodium sulfate.The filtrate was concentrated in vacuo to give a crude mixture, which was purified by column chromatography (SiO2, CHCl3_hexane=1:4) toafford compound 3 (2.4 g, 54.5%) as a white solid.1H NMR (400 MHz, CDCl3) delta (ppm): 7.87 (d, J=8.3 Hz, 1H), 7.80(d, J=7.6 Hz, 2H), 7.43-7.32 (m, 5H), 7.28-7.18 (m, 3H), 6.97-6.89(m, 2H), 6.60-6.52 (m, 2H), 6.46-6.30 (m, 4H), 2.54 (s, 3H). 13C NMR(100 MHz, CDCl3) delta (ppm): 156.55, 141.22, 140.97, 140.20, 139.18,134.94, 133.41, 130.11, 128.35, 127.86, 127.58, 127.20, 125.73,124.77, 120.71, 119.89, 114.50, 56.72, 23.16.
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-Bromo-4-iodo-2-methylbenzene, other downstream synthetic routes, hurry up and to see.
