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
非均相Amberlyst-15催化剂对活化的芳烃或杂芳烃与α-酰胺基砜之间的Friedel-Crafts反应具有有效的催化性能。用1,2,4-三甲氧基苯处理的各种α-酰胺基砜使Friedel-Crafts反应产物的收率非常高。与杂芳烃的反应显示出中等产率的产物。该催化剂可以容易地再循环而没有明显的活性损失。
