  • Abstract

    A greener approach for the preparation of fluoro-aromatics by diazotization of aromatic amines followed by thermal decomposition of derived tetrafluoroborate in ionic liquids has been developed. The advantages of this procedure are simplicity of reaction, no workup, high purity of the product, safer process, low waste effluents and commercializable processes with recyclability of ionic liquids
