61326-44-1, 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. 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.
4 g of 3-methoxycarbonylbenzene borate, 1 g of 4Br-TPE and 0.47 g of tetratriphenylphosphine The palladium was uniformly mixed, vacuumed for 5 min and nitrogen-filled for 5 min for 3 times. 100 mL of a toluene ethanol solution with a volume ratio of 9:1 and 12 mL of a 1 mol/L solution of tripotassium phosphate were injected and refluxed at 110 ¡ã C for 24 h until the starting of the reaction. . The mixture was cooled to room temperature, filtered (dichloromethane), and the filtrate was evaporated to dryness.Finally, the column is treated to obtain pure 1,1,2,2-tetra[[3-benzomethoxycarbonyl)benzene]ethylene;
The synthetic route of 61326-44-1 has been constantly updated, and we look forward to future research findings.
