Reference of 18014-00-1, 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. 18014-00-1, name is Dimethyl 2,5-dibromoterephthalate belongs to esters-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
2.59 g of compound 2 and 880 mg of 2,5-dibromoterephthalate were dissolved in 100 mL of freshly distilled tolueneMouth,Then, 400 mg of Pd (PPh3) 4 and 330 mg of CuI were added thereto under a nitrogen atmosphere,Heated to reflux for 8-12 hours. After completion of the reaction, the mixture was cooled to room temperature, the reaction solution was poured into water,Extracted with toluene twice, the organic phase was combined, dried, filtered and spin dried to obtain the crude product,The resulting crude product was purified by silica gel column to give 996 mg of compound 3 (84%).
The synthetic route of Dimethyl 2,5-dibromoterephthalate has been constantly updated, and we look forward to future research findings.
