AMMONIUM NICKEL SULFATE (TUTTONS SALT) MEDIATED RAPID AND FACILE SYNTHESIS OF SCHIFF BASE UNDER ENVIRONMENTAL FRIENDLY CONDITION

In the present study a rapid and facile method for the synthesis of schiff bases (3a-z & 3aa-af) has been developed by using Ammonium Nickel Sulfate (ANS) (Tuttons Salt) as catalyst. Further more, the reaction is selective as only benzaldehydes are reacted where as acetophenone failed to perform this reaction. The present method is very rapid with simple work up and gives the products in good to excellent yield. The reaction is totally carried out under environmentally friendly condition by using green solvent MeoH and water in 1:1 ratio. Thus it is anticipated that the present newly developed method will give ample chemical space to the chemist to prepare the Schiff bases in rapid and envirnmentaly benign conditions.
