Reference of 1313876-00-4, 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. 1313876-00-4, name is 4,7-Dibromo-5,6-bis(dodecyloxy)benzo[c][1,2,5]thiadiazole belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
4,7-dibromo-5,6-bis (dodecyloxy) benzo [c] [1,2,5] thiadiazole(2.65 g, 4 mmol),Compound A-1 (5.53 g, 10 mmol),Pd (PPh3) 4 (0.23 g, 0.2 mmol),25 mL of dimethylformamide (DMF) was added to toluene (75 mL), and the mixture was heated at 90, 100, and 110 C for 48 hours.After cooling the reaction, the residue was precipitated in methanol and filtered. The separated organic layer was washed with water. Thereafter, the mixture was subjected to vacuum distillation and purified by flash chromatography with methylene chloride and chloroform. The solid was washed with a large amount of methanol and dried under vacuum for 24 hours. To obtain a dark violet powder compound 1-1 (4.3 g, 84%).
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, 4,7-Dibromo-5,6-bis(dodecyloxy)benzo[c][1,2,5]thiadiazole, other downstream synthetic routes, hurry up and to see.
