The heterogeneous Amberlyst-15 catalyst displays efficient catalytic properties for the Friedel–Crafts reactions between an activated arenes or heteroarenes and α-amido sulfones. Various α-amido sulfones on treatment with 1,2,4-trimethoxy benzene give the Friedel–Crafts reaction products in very good yield. The reactions with heteroarenes show moderate yield of the product. The catalyst can be easily
