As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 61326-44-1, name is 1,1,2,2-Tetrakis(4-bromophenyl)ethene belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
(3) The third step: under argon protection, add to the double-mouth bottle4,4 ‘, 4 “, 4” -tetrabromostatrene,Dimethoxydianiline, palladium acetate, sodium tert-butoxide, tri-tert-butylphosphine,The reaction was stopped for 27 hours. The reaction was quenched. Saturated ammonium chloride solution was added and the mixture was extracted three times with dichloromethane. The organic layer was dried over anhydrous MgSO4. The crude product was purified by silica gel column chromatography ( Petroleum ether: dichloromethane: ethyl acetate = 6: 1: 0.5, v / v) to give a yellow solid which was recrystallized from tetrahydrofuran / petroleum ether. The product TPE-OMe-oo, the product of the formula is shown in formula (VII):
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, 1,1,2,2-Tetrakis(4-bromophenyl)ethene, other downstream synthetic routes, hurry up and to see.
