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-Dibromo-5-(tert-butyl)benzene, other downstream synthetic routes, hurry up and to see.
Reference of 129316-09-2, 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. 129316-09-2, name is 1,3-Dibromo-5-(tert-butyl)benzene belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
4-phenyl-3,5-dimethylpyrazole (2.0680 g, 12 mmol, 1.0 eq.) was added sequentially to a dry three-necked flask with a magnetic rotor.1,3-Dibromo-5-tert-butylbenzene (7.1513 g, 24 mmol, 98%, 2.0 eq.), cuprous iodide (0.2971 g, 1.56 mmol, 0.13 eq.),Potassium phosphate (5.0945g, 24mmol, 2.0 equivalents) and trans-N,N’-Dimethyl-1,2-cyclohexanediamine (0.4528 g, 3.12 mmol, 98%, 0.26 eq.).Nitrogen was purged three times, then dimethyl sulfoxide (18 mL) was added under nitrogen.The reaction vial was then placed in a 120 C oil bath.After stirring for 5 days, it was cooled to room temperature, filtered through Celite, and ethyl acetate (30 mL¡Á3) was washed thoroughly.The obtained filtrate was washed with brine (20 mL¡Á2), and then evaporated and evaporated.All organic phases were combined and dried over anhydrous sodium sulfate. Filtration, concentration, and purification of the crude product by flash chromatography on silica gel column chromatography(Eluent: petroleum ether / ethyl acetate = 30/1 to 15/1) Intermediate 5 was obtained as a pale yellow oil, 2.5293 g, yield 55%.
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-Dibromo-5-(tert-butyl)benzene, other downstream synthetic routes, hurry up and to see.
