ABSTRACT:
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 a substantially 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.
