Abstract An efficient, fast and straightforward procedure for the synthesis of aryltriazenes is 
described in the present paper by using aryl diazonium silica sulfates and secondary 
amines. Using the present method, different kinds of aryl diazonium silica sulfates, 
containing electron withdrawing groups as well as electron donating groups, were rapidly 
converted to the corresponding of aryltriazenes in good yield and short reaction time. These 
reactions were carried out in water at room temperature under mild and heterogeneous ...
