Category: 626-39-1

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. 626-39-1, name is 1,3,5-Tribromobenzene belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Computed Properties of C6H3Br3

In a 100 mL-flask, 3.84 g (30 mmol) of compound 15, 3.14 g (10 mmol) of compound 16, 2 mol/L of potassium carbonate 4 mL, 60 mL of tetrahydrofuran were added, and then oxygen was removed by bubbling for 30 min, and then 0.1 g was added.(0.09 mmol) tetrakistriphenylphosphine palladium, stirred under nitrogen at 80 C under reflux for 12h, cooled, then added ethyl acetate 20mL, the organic phase was washed with ice water 3 times, dried over anhydrous sodium sulfate, and then filtered to evaporate the filtrate The crude product was purified by silica gel column chromatography to give 2.36 g of compound 17, a yield of 73%.

The synthetic route of 626-39-1 has been constantly updated, and we look forward to future research findings.

626-39-1, Adding a certain compound to certain chemical reactions, such as: 626-39-1, name is 1,3,5-Tribromobenzene, belongs to bromides-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 626-39-1.

Carbazole (6.6 g, 39.7mmol), 1,3,5-tribromobenzene (5 g, 15.9mmol), cuprous iodide (0.3 g,1.6 mmol), potassium phosphate (13.7 g, 64.5 mmol) and trans-1,2-cyclohexanediamine(1.6 g, 15.9 mmol) were dissolved in 200 mL of 1,4-dioxane. After the mixed solution wasstirred in a nitrogen atmosphere for 19 h at 110C, the reaction mixture was cooled to roomtemperature. The mixture extracted with dichloromethane (80 mL ¡Á 3 times) and driedover anhydrous MgSO4. The crude product was subjected to flash column chromatography(dichloromethane: n-hexane = 1: 4) to give compound (1) (6.3 g, 79%). 1H NMR (CDCl3,300MHz); delta = 7.68 (d, -CH-), 7.5 (d, -CH-), 7.45 (d, -CH-), 7.35 (m-CH-), 7.29(t, -CH3),7.18(m, -CH-).

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, 1,3,5-Tribromobenzene, other downstream synthetic routes, hurry up and to see.
