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. 2062-98-8, name is Perfluoro(2-methyl-3-oxahexanoyl) fluoride belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. 2062-98-8
Put 0.51 g (4.2 mmol) of 4-ethylphenol into a three-necked flask, add 20 mL of dichloromethane, and add 1.99 g (6 mmol) of hexafluoropropylene oxide dimer (CF3CF2CF2OCF (CF3 ) COF, provided by Zhejiang Huanxin Fluorine Materials Co., Ltd., recorded as FEOCOF), after the addition, add 0.05mL (0.0007mmol) N, N-dimethylformamide (DMF), and slowly add 0.4mL ( 0.003 mmol) dry triethylamine,After the dropwise addition was completed, the reaction was stirred at 40 C. for 2 h.After the reaction, 20 mL of deionized water was added and extracted with dichloromethane (20 mL ¡Á 3). The organic phases were combined and dried over MgSO 4, filtered, and rotary evaporated to obtain a crude product. The crude product was separated by silica gel column chromatography (eluted with petroleum ether). Agent) to obtain a colorless slightly viscous liquid, that is, the target product, with a yield of 99.1%.
The synthetic route of 2062-98-8 has been constantly updated, and we look forward to future research findings.
