Electric Literature of 112671-42-8, The chemical industry reduces the impact on the environment during synthesis 112671-42-8, name is 4-Bromo-1-iodo-2-nitrobenzene, I believe this compound will play a more active role in future production and life.
A sealed tube was charged with CuI (0.19g, 1.0mmol, 2.5 equiv.), AgF (0.13g, 1.0mmol, 2.5 equiv.), pyridine (0.27mL, 8.3 equiv.), various iodoarenes (0.4mmol, 1.0 equiv.), triethyl(1,1,2,2-tetrafluorobut-3-en-1-yl)silane (4 : 0.19g, 0.8mmol, 2.0 equiv.) and DMF (3.2mL, 0.25M) in glove box. The sealed tube was brought under an atmosphere of argon and capped. The resulting mixture was stirred at 60C for 16h, and then cooled room temperature. The resulting mixture was passed through short column. The eluent was concentrated in vacuo to give the crude materials, which were purified by silica gel column chromatography, leading to the desired coupling products
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-Bromo-1-iodo-2-nitrobenzene, other downstream synthetic routes, hurry up and to see.
