4-Bromobenzaldehyde may be prepared in the laboratory in two steps by oxidation 4-bromotoluene. [4] In the first step, two bromine atoms are added to the methyl group of 4-bromotoluene by free radical bromination to form 4-bromobenzal bromide.
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.
It is considerably more polar than benzene, with a dielectric constant of 5.42 compared to 2.28 for benzene at 298 K. [4] Fluorobenzene is a relatively inert compound reflecting the strength of the C–F bond. Although it is usually considered a non-coordinating solvent, a metal complex of PhF has been crystallized. [5]
Two other isomers are also known: 2-trifluoromethylbenzaldehyde and 3-trifluoromethylbenzaldehyde. These compounds are derivatives of benzaldehyde with trifluoromethyl substituents. The CF 3 group enhances the electrophilicity of the formyl group and provides a label for analysis by fluorine-19 nuclear magnetic resonance spectroscopy .
β-Nitrostyrene is a chemical precursor for slimicides and dyes. Specifically bromo-nitrostyrene is obtained upon treatment with bromine followed by partial dehydrohalogenation [2] while 2-nitrobenzaldehyde is obtained by treatment with ozone respectively.
An example involves the conversion of the ethyl ester of 5-bromovaleric acid to the iodide: [4] EtO 2 C(CH 2) 4 Br + NaI → EtO 2 C(CH 2) 4 I + NaBr. Potassium fluoride is used for the conversion of chlorocarbons into fluorocarbons. [5] Such reactions usually employ polar solvents such as dimethyl formamide, ethylene glycol, and dimethyl ...
