PERIODATE OXIDATION OF AQUA-N-(2-ACETAMIDO)IMINODIACETATO-COBALT(II) COMPLEX INVOLVING MALEIC ACID CO-LIGANDS

摘要

The kinetics of oxidation of the ternary complexes [Co-II(ADA)(L)(H2O)](2-) (ADA = N-(2-acetamido)iminodiacetate, L = maleic acid) by periodate has been investigated spectrophotometrically in aqueous medium over 30-50 degrees C range, pH 3.72-4.99 and I=0.2 mol dm(-3). The reaction was carried out under pseudo-first order conditions by using a tenfold excess of [IO4-] over [Coll(ADA)(L)(H2O)(2-). The kinetics of oxidation of [Co-II(ADA)(L)(H2O)](2-) obeyed the rate law:
