Reference of 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.
the intermediate 14 (1.30g, 2mmol), intermediate 5 (4.44g, 12mmol), four (triphenylphosphine) palladium (280 mg, 0 . 24mmol) and sodium carbonate (1.06g, 10mmol) added to the reaction in the bottle, the substitute gas three times, under the protection of nitrogen injection THF (80 ml) and H2 O (20 ml), 80 °C heating reflux reaction 24h. Water quenching reaction, by methylene chloride extraction, after concentrating makes the powder, eluent for (petroleum ether/dichloromethane=10/1) column, to obtain the final product TPE – TB, yield 85percent.
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.
