Adding a certain compound to certain chemical reactions, such as: 17715-69-4, name is 1-Bromo-2,4-dimethoxybenzene, belongs to ethers-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 17715-69-4, Computed Properties of C8H9BrO2
General procedure: A solution of 4-methoxybromobenzene (2.67 mmol)and cyclopent-2-en-1-one (3.2 mmol) in DMSO was stirred at ambient temperaturefor 10 min under nitrogen, and treated with Na2CO3 (8.01mmol) and tri-tert-butylphosphonium tetrafluoroborate (0.53 mmol).The reaction mixture was degassed with nitrogen for 10 min and treated withPd(PPh3)2Cl2 (0.13 mmol) and X-Phos (0.26mol), and stirred at 100 0C for 12 h. The reaction mixture was cooledto ambient temperature, diluted with water, and extracted with AcOEt (3 x 50ml). The combined organic layers were washed with brine, dried over anhydrousNa2SO4, and evaporated. Flash chromatograph on silica gel(AcOEt:cyclohexane 1:3) provided the Heck coupling product as brown solid (340mg, 68percent).
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-Bromo-2,4-dimethoxybenzene, other downstream synthetic routes, hurry up and to see.
