AbstractThis article covers the preparation, properties, reactions, and applications of three types of fluorinated aromatic compounds: ring‐fluorinated aromatics, side‐chain fluorinated aromatics and arylfluoroalkyl ethers, and fluorinated nitrogen heterocyclics.The special properties conferred by fluorine justify the higher costs required to produce fluoroaromatics. Depending on which substituents are present, fluoroaromatic intermediates can be converted into fluorinated or fluorine‐free commercial end products. Fluorine‐containing aromatics have been incorporated into drugs (hypnotics, tranquilizers, antiinflammatory agents, analgesics, antibacterials) and into crop‐protection chemicals (herbicides, insecticides, fungicides). Liquid crystals, positron emission tomography, and imaging systems represent new areas where fluoroaromatics and fluoroheterocyclics have gained attention.For fluorine‐free end products, the lability of fluorine in fluoronitrobenzenes and other activated molecules permit it to serve as a handle in hair dye manufacturing operations, high performance polymers (eg, PEEK), drugs (eg, diuretics), fiber‐reactive dyes, analytical applications, and biological diagnostic reagents.
