| Abstract: | The reaction of S(lV) with pyruvato(pentaamrnine)cobalt(III) has been studied in the range of pH (3.2 - 6.5) and temperatures (15 - 30°C). There is no evidence of substitution of bound carboxylate by sulphite. However, the keto form of the pyruvato complex reacts with HSO3- and SO32- yielding the S(IV) addition product, (NH3)5CoO2CC(SO3)(OH)CH3. The rate constants and activation parameters for both HSO3- and SO3 2- reaction paths are reported. The pyruvato complex and also its sulphite addition product do not undergo reduction of cobalt(III) centre by sulphite. |
