Synthesis ,Spectral Investigation, Anticancer Study of Azo-Imine Heterocyclic Compounds
Abstract: Many Schiff base reactions are known within a famous series of addition reactions to the azomethine group, where reagents are added to the polarized double bond and the nucleophilic (nucleophilic) reagents attack the carbon atom in the azomethine bond.. An example of this type of reaction is the addition of alkyl halides, which produces quaternary amine salts, which in turn are converted to the secondary amine. These compounds have an …
