Substituted fluorobenzenes.

摘要

Introduction of a fluoro substituent into an aromatic ring adjacent an electron donating group is difficult producing mixed isomers and low yields of desired products. A process for the introduction of a fluoro substituent into substantially in an adjacent position to an electron-donating group into an aromatic compound in high yield is disclosed. The fluoroaromatic compounds are useful as synthetic intermediates for example in the manufacture of agrochemicals, pharmaceuticals and dyestuffs.
