Hot Sale 85070-48-0 Manufacturer 3-Chloro-2-fluorobenzaldehyde Supplier
3-chloro-2-fluorobenzaldehyde is a useful intermediate in medicinal chemistry and organic synthesis, such as herbicides, synthetic intermediates for plant growth regulators. In a synthetic transformation, the aldehyde group in the structure can be easily converted to a hydroxyl group, or an imine structure; It can also be oxidized to the corresponding benzoic acid product. In addition, the halogen atom on the benzene ring may undergo a coupling reaction followed by derivatization at the 2,3 position of the benzene ring.
to trans 3-(2-fluoro-3-chlorophenyl) to a solution of methyl -2-acrylate ((64mg,0.13mmol) in tetrahydrofuran (3ml) was added a solution of lithium hydroxide (16mg,0.65mmol) and after stirring overnight, acidify the reaction with 2m
HCl, filter the precipitate and dry under vacuum, add diethyl ether and water to the residue, separate the organic layer, and dry the mixture over anhydrous sodium sulfate, the sodium sulfate solid was removed by filtration, the solvent was evaporated, and the residue was purified by column chromatography with (EtOAc/hexane = 3:7) to give 3-chloro-2-fluorobenzaldehyde.
