I am trying to synthesize hydroxy acetyl coumarin schiff base complexes via different metals. common reported procedures for complex synthesizing did not result in any conclusion. any suggestions???
Take metal salt dissolve in aqueous ethanolic solution (15 ml) , then add equimolar quantity of the schiff,s base der. of coumarin dissolved in ethanol & heat the reaction mixture on water bath for 1 hr. , stirr frequently while heating & cool, neutralize the mixture using 1:1 ammonia. The Schiff,s base complex precipitates out as a solid.
