| Abstract: | The UV spectra of some chlorinated o-hydroxyschiff bases were studied in different solvents. It was found that schiff bases derived from condensation of 2-hydroxybenzaldehyde or 5-chloro-2-hydroxy benzaldehyde with substituted aniline exist as enol form, whereas schiff bases derived from the condensation of 3,5-dichloro-2-hydroxybenzaldehyde with substituted aniline exist as enol form, whereas schiff bases derived from the condensation of 3,5-dichloro-2-hydroxybenzaldehyde with aniline exist as keto form especially in dimethyl sulfoxide. The ratio of enol/keto isomers were calculated for these schiff bases. |
