| Abstract | ||
| The prepared compound 2-amino -5-mercapto -1,3,4-thiadiazol (1) was converted to hydrazineo derivative(2)by the reaction with hydrazine hydrate Compound(2) was reacted with phthalic anhydride to give phthalazine derivative(3)and also maleic anhydride to give pyridazine derivative(4 ). The amino group in these derivatives was converted to azo group (N=N) andazomethine (C=N)(shiffs base ) . Respectively using different aromatic phenol such as (resorcinol) and also different aromatic aldehydes such as (p- hydroxyl benzaldehyde , p- N,N-Di methyl benzaldehyde , p chlorobenzaldehyde). The prepared compounds were identified using melting point apparatus , I.R- spectro photo meter and H1-N.M.Rspectrophotometerfor compound (5,10,14). | ||
