Application of 3824-21-3, 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. 3824-21-3, name is 2-Fluoro-4-iodo-1-methoxybenzene belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
2-fluoro-6-iodo-3-methoxybenzoic acidInto an 100-mL 3-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed a solution of 2-fluoro-4-iodo-1-methoxybenzene (5.00 g, 19.84 mmol, 1.00 equiv) in tetrahydrofuran (40 mL) with stirring at -78 C. This was followed by the addition of LDA (1.8 N, 11 mL, 1.10 equiv, in THF solution) dropwise at -78 C. The resulted solution was stirred for 1h at -78 C. Carbon dioxide was bubbled into the reaction solution with stirring. The reaction mixture was warmed up to room temperature and stirred overnight. Then it was concentrated under vacuum and diluted with sodium hydroxide aqueous solution (30 mL, 4N). The mixture was extracted with 30 mL of ethyl acetate. The pH value of the aqueous phase was adjusted to 2.0 with 2N hydrochloride aqueous solution. The resulted solution was extracted with 3×50 mL of ethyl acetate. The organic layers were combined and concentrated under vacuum. This resulted in 3.10 g (53%) of 2-fluoro-6-iodo-3-methoxybenzoic acid as light yellow solid. LC-MS (ESI) m/z: calculated for C8H6FIO3: 296. found: 295[M-1]-.
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, 2-Fluoro-4-iodo-1-methoxybenzene, other downstream synthetic routes, hurry up and to see.
