Adding a certain compound to certain chemical reactions, such as: 459424-72-7, name is 1,2,3-Trifluoro-4-iodobenzene, belongs to iodides-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 459424-72-7, category: iodides-buliding-blocks
To a solution of diisopropylamine (4.3 g, 42.6 mmol) in THF (50 ml) was added n-butyl lithium (21.3 ml, 2 N in hexane) dropwise at -10 0C, and the solution was stirred for 30 minutes at -10 0C. The reaction mixture was cooled to -78 0C and to this was added l,2,3-trifluoro-4- iodobenzene (5 g, 19.38 mmol) in THF (50 ml), stirred at -78 0C under a nitrogen atmosphere. After stirring for 5 hours at this temperature, DMF (7 ml, 89 mmol) was added dropwise such that the temperature was maintained below -60 0C. The reaction mixture was slowly allowed to warm to room temperature and stirred overnight. The reaction mixture was treated with saturated aqueous NH4Cl solution and the aqueous layer extracted with ethyl acetate (2 X 100 ml). The organic phases were combined, dried over anhydrous sodium sulfate, and concentrated. The
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, 1,2,3-Trifluoro-4-iodobenzene, other downstream synthetic routes, hurry up and to see.
