Fluoroanilines

Fluoroanilines are a group of organic compounds that are derivatives of aniline where one or more hydrogen atoms on the benzene ring have been replaced by fluorine atoms. They are classified by the position of the fluorine atom(s) relative to the amino group. Common examples include 2-fluoroaniline, 3-fluoroaniline, and 4-fluoroaniline, where the numbers denote the position on the ring. Polysubstituted fluoroanilines also exist.

These compounds are typically colorless to pale yellow liquids or solids. The presence of fluorine significantly alters the electronic properties and reactivity of the aniline molecule. Fluorine is a highly electronegative atom, which can influence the basicity of the amino group and the susceptibility of the aromatic ring to electrophilic substitution.

Fluoroanilines serve as important intermediates in the synthesis of various organic molecules. They are utilized in the production of pharmaceuticals, agrochemicals, dyes, and polymers. For example, they can be incorporated into the structures of drugs to enhance their metabolic stability or alter their binding affinity to biological targets. The specific isomer and its properties dictate its utility in different synthetic pathways.
