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. 2265-91-0, name is 1,3-Difluoro-5-iodobenzene belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Computed Properties of C6H3F2I
General procedure: To a solution of tetrabutylammonium bromide (1.100 g, 3.33 mmol), potassium acetate (0.586 g, 3.57 mmol), and palladium acetate (0.025 g, 0.11 mmol) in DMF (20 mL) were added substituted iodobenzene (2.21 mmol) and 4-acetyloxystyrene (2.44 mmol). The reaction mixture was recharged with Argon and stirred at 80C for 5 h in a sealed tube. The mixture was extracted with ethyl acetate. The organic layer was washed with saturated aqueous NaCl and concentrated in vacuo. The residue was purified by column chromatography on silica gel (petroleum ether/ethyl acetate, 10:3) to afford the intermediate substituted (E)-4-styrylphenyl acetate. To a solution of triethylamine (2.0 mL) in MeOH (5 mL) was added substituted (E)-4-styrylphenyl acetate (1.36 mmol). The reaction mixture was stirred at reflux temperaturefor 3 h. The mixture was extracted with ethyl acetate. The organic layer was washed with saturated aqueous NaCl and concentrated in vacuo. The residue was purified by column chromatography on silica gel (dichloromethane/methanol, 10:0.3) to afford pure product.
The synthetic route of 2265-91-0 has been constantly updated, and we look forward to future research findings.
