Reference of 1124-63-6, 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. 1124-63-6, name is 3-Cyclohexylpropan-1-ol. A new synthetic method of this compound is introduced below.
(9-1) Synthesis of 3-bromopropylcyclohexane (compound 9-1) [Show Image] 3-Cyclohexyl-1-propanol (5.00 g) was dissolved in methylene chloride (50 ml), triphenylphosphine (10.2 g) and N-bromosuccinimide (6.90 g) were added under ice-cooling, and the mixture was stirred under ice-cooling for 1 hr, and further at room temperature for 1 hr. The reaction mixture was washed with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. Diethyl ether (100 ml) was added, and the precipitated triphenylphosphine oxide was filtered off. The concentrate of the filtrate was purified by silica gel column chromatography (hexane alone) to give the object product (7.17 g) as a colorless oil. 1H-NMR(CDCl3) delta (ppm): 0.81-0.96(2H, m), 1.10-1.45(6H, m), 1.60-1.78(5H, m), 1.82-1.92(2H, quint, J=7.0Hz), 3.39(2H, t, J=7.0Hz).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,1124-63-6, 3-Cyclohexylpropan-1-ol, and friends who are interested can also refer to it.
