FRIEDEL-CRAFTS REACTION WITH FECL3-GRAPHITE

The Friedel-Crafts alkylation of benzene with tert-butyl chloride has been investigated in the presence of FeCl3-graphite and anhydrous FeCl 3 catalysts. The FeCl3-graphite leads to a decrease in the rate of rea ction. However, the selectivity of the transformation increases, i.e, decrease of disubstitution occurs. FeCl3-graphite was reused three tim es exhibiting a drop in activity by about a half. In the acylation of benzene with acetyl chloride under the above conditions, the yield of acetophenone was roughly twice as high with FeCl3-graphite compared wi th anhydrous FeCl3.
