Abstract: A novel modified active carbon surported ferric chloride catalyst(MAC-Fe Cl3) has been developed, which has been characterized by IR and ICP. MAC-Fe Cl3 exhibited excellent catalytic activities for one-pot synthesis of 2,4,5-triaryl imidazoles and 1,2,4,5-tetraaryl imidazoles from ammonium acetate, benzil, aromatic aldehydes or primary amines. The catalyst could be recycled easily and the activity of catalyst maintains stability after reused for 4 times, which makes this methodology has the advantages of good yields, less pollution and simple work-up.
