Analyzing the synthesis route of 2-Chloro-4-(trifluoromethyl)benzyl alcohol

The synthetic route of 56456-51-0 has been constantly updated, and we look forward to future research findings.

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. 56456-51-0, name is 2-Chloro-4-(trifluoromethyl)benzyl alcohol, the common compound, a new synthetic route is introduced below. SDS of cas: 56456-51-0

To a solution of 2-chloro-4-trifluoromethylbenzyl alcohol (38.8 g) and pyridine (3.0 ml) in diethyl ether (320 ml)- tetrahydrofuran (80 ml) was added thionyl chloride (32.8 g) , and the mixture was stirred at room temperature for 15 hr. The reaction solution was concentrated, water was poured’ into the residue and the mixture was extracted with ethyl acetate. The o ethyl acetate layer was washed with IN hydrochloric acid, a saturated aqueous sodium hydrogencarbonate solution and saturated brine, dried (MgSO4), and concentrated. The residue was subjected to silica gel column chromatography, and eluted with ethyl acetate-hexane (1:25 – 1:12, v/v) to give 2-chloro- 4-trifluoromethylbenzyl chloride (38.9 g, yield: 92%) as a colorless oil.1H-NMR (300 MHz, CDCl3) delta:4.72 (2 H,, s) , 7.51 – 7.57 (1 H, m) , 7.60 – 7.70 (2 H, m) .

The synthetic route of 56456-51-0 has been constantly updated, and we look forward to future research findings.

Analyzing the synthesis route of 2-Chloro-4-(trifluoromethyl)benzyl alcohol

With the rapid development of chemical substances, we look forward to future research findings about 56456-51-0.

As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 56456-51-0, name is 2-Chloro-4-(trifluoromethyl)benzyl alcohol, molecular formula is C8H6ClF3O, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. Recommanded Product: 2-Chloro-4-(trifluoromethyl)benzyl alcohol

Reference Example 130 To a solution of 2-chloro-4-(trifluoromethyl)benzyl alcohol (2.23 g) and triphenylphosphine (4.17 g) in tetrahydrofuran (25 ml) was added carbon tetrabromide (5.27 g), and the mixture was stirred at room temperature for 2 hr. The reaction solution was concentrated, hexane and diethyl ether were added to the residue, and the insoluble substance was removed by filtration. The filtrate was concentrated, and the obtained residue was subjected to silica gel column chromatography and eluted with ethyl acetate-hexane (0:1 to 1:4, v/v) to give 2-chloro-4-(trifluoromethyl)benzyl bromide (2.90 g, yield 99%) as a colorless oil. 1H-NMR (300 MHz, CDCl3) delta:4.59 (2 H, s), 7.46 – 7.60 (2 H, m), 7.65 (1 H, s).

With the rapid development of chemical substances, we look forward to future research findings about 56456-51-0.
