Azo-Hydrazo Tautomerism: Further Evidence Based On Polarographic Reduction And Acidity Function Of Some Heterocyclic Compounds Containing Oximino-Group
( 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 ... -
Electrochemical behaviour of some pyrimidine derivatives: polarographic reduction of 1, 3-dimethyl-2, 4, 6(1h, 3h, 5h) pyrimidinetrione and its substituted 5-phenylazo
( Qatar University , 1994 , Article)The polarographic behaviour and spectrophotometric pKa of 1,3-dimethyl barbituric acid and 5-phenylazo substituted products were investigated in buffer solution of pH ~ 2-11. The results revealed an azo form of the substituted ...
