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.
