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. 615-59-8, name is 1,4-Dibromo-2-methylbenzene, A new synthetic method of this compound is introduced below., Product Details of 615-59-8
(1) 2,5-dibromotoluene (10 mmol, 2.5 g), 4-methoxycarbonylbenzeneboronic acid (24 mmol, 4.33 g) under N2 protection.caesium fluoride (40 mmol, 6.0 g) was placed in a 250 mL three-necked flask, and 5% (1.2 to 2.0 g) of Pd (PPh3) catalyst was added.100 mL of anhydrous THF was used as a solvent, and refluxed at 67 C.After completion of the reaction, the product was isolated by silica gel column chromatography (petroleum ether, dichloromethane) to give a pink solid 2.91 g, yield 81%.
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.
