Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 22034-13-5, name is 4-Bromobenzo[c][1,2,5]thiadiazole, A new synthetic method of this compound is introduced below., Product Details of 22034-13-5
A mixture of 2,7-bis-boronic acid pinacol ester-4-hexylcarbazole-9,9-diarylfluorene (0.2 g, 0.24 mmol, 1 equiv), 4-bromo-2,1,3-thiadiazole (0.206 g, 1 mmol, 4 equiv) were dissolved in 15 ml of a dry bubbling packed with tetrahydrofuran in N2, 5 ml of potassium carbonate aqueous solution (2 mol / L), followed by the addition of 40 mg of palladium catalyst tetraphenylphenylphosphine The reaction mixture was heated at 85 ¡ã C for 24 h and extracted with methylene chloride. After drying, the mixture was purified by rotary distillation using petroleum ether: dichloromethane = 4: 1 silica gel to give a powdery solid in 68percent
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
