Fluorobenzaldehyde can be used as a synthetic intermediate because the fluorine can be replaced via oxidation reaction. [1] Due to the aldehyde group, the fluorobenzaldehydes can be used to make a variety of schiff base compounds through a condensation reaction , some of which have antimicrobial properties.
The isomers which have been cited as examples of metamers in chemical literature consist primarily of ethers; [3] but this could by the same reasoning be extended to thioethers, secondary as well as tertiary amines, esters, secondary as well as tertiary amides, (mixed) acid anhydrides etc. Metamers in organic chemistry
2-Chloro-6-fluorobenzaldehyde is prepared by oxidation of 2-chloro-6-fluorotolulene by chromyl chloride. [3] It reacts with sodium hydroxide to give a mixture of 2-chloro-6-fluorobenzene and 6-chlorosalicaldehyde. [4] 2-Chloro-6-fluorobenzaldehyde is used in the production of the antiseptics dicloxacillin and flucloxacillin.
Substituents add ortho to the amine in diethyl-(meta-trifluoromethyl)aniline and ortho to the fluoride in para-fluorobenzaldehyde; When multiple substituents are comparably activating, steric hindrance dominates regioselectivity. Substituents add ortho to the methyl group in para-(tert-butyl)toluene
Care must be taken to avoid cocrystallisation of the ortho isomer. [2] Many nitro compounds' ortho and para isomers have quite different boiling points. These isomers can often be separated by distillation. These separated isomers can be converted to diazonium salts and used to prepare other pure ortho or para compounds. [3]
