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. 50638-46-5, name is 4-Bromo-3-chloroanisole, A new synthetic method of this compound is introduced below., Safety of 4-Bromo-3-chloroanisole
A 1.6M solution of n-butyllithium in hexane (4 ml) was added to a solution of 4-bromo-3-chloroanisole (CAS Reg. No. 50638-46-5, 1.3 g) in THF (20 ml) at -78 C. The mixture was stirred for 30 min at -78 C. Acetaldehyde (0.7 ml) was added to the mixture. The mixture was allowed to warm to room temperature. Water (50 ml) was added and extracted with DCM. The combined organic layers were dried over Na2SO4 and concentrated to an oil to give the title compound (983 mg) as colorless oil. MS (m/e)=186 [M+].
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.
