Synthesis and characterisation of lanthanon (III) chelates of O-(N-α-oxindolimino) benzoic acid and O-(N-α-oxindolimino) propanoic acid possessing N-N-O moiety

摘要

SchIff bases derived from the condensation of oxindole with antbranillic acid and β-alanine and their lanthanon (III) chelates have been synthesized and characterized by physicochemical techniques, Potentiometric studies have been carried out by Irving-Ro
