Introduction 2-acetylated thiophene,furan,pyrrole,pyridine are very important intermediates for the fine chemicals such as drugs and pharmaceuticals,flavouring agents for food stuffs [1,2].These compounds are generally produced by the conventional acetylation process,the famous Friedel-Crafts acetylation reaction,which is an electrophilic substitution reaction and takes place in the presence of Lewis acid-metal chlorides and some other solid catalysts,such as anhydrous AlCl3 [3-5].
