Comparison of different Lewis acid supported on hydroxyapatite as new catalysts of Friedel–Crafts alkylation Original Research Article

ZnCl2, NiCl2 and CuCl2 supported on hydroxyapatite (HAP), as a new solid support, catalyse the Friedel–Crafts alkylation of benzene, toluene and p-xylene by benzyl chloride. The reaction proceeds selectively to monoalkyl-compounds and in a short reaction time. The best catalytic activities were observed with the zinc catalysts.
