Azo-Hydrazo Tautomerism: Further Evidence Based On Polarographic Reduction And Acidity Function Of Some Heterocyclic Compounds Containing Oximino-Group
Helmy, Ahlam M. A. [احلام عباس حلمي]; El-Shafei, Alaa; Migahed, M. A.; Morsi, M. A. ( Qatar University , 1994 , Article)Potentiometric pKa and polarographic behaviour of l,3-indandione-monoxime-2-phenyl azo and four of its substituted derivatives were investigated in buffer solution of pH -2-12. The results showed that the compounds are in ...
