Mechanistic Investigation of Uncatalyzed and Osmium(VIII) Catalyzed Oxidation of Guanidine by Ag(III) Periodate Complex in Aqueous Alkaline Medium: A Comparative Kinetic Approach

Mechanistic Investigation of Uncatalyzed and Osmium(VIII) Catalyzed Oxidation of Guanidine by Ag(III) Periodate Complex in Aqueous Alkaline Medium: A Comparative Kinetic Approach

The oxidation of guanidine hydrochloride (GH) by diperiodatoargentate(III) (DPA) has been investigated both in the absence and presence of [Os(VIII)] catalyst in alkaline medium at a constant ionic strength of 0.10 mol dm−3 spectrophotometrically. The oxidation products were identified by spectral s...

Zusammenfassung:The oxidation of guanidine hydrochloride (GH) by diperiodatoargentate(III) (DPA) has been investigated both in the absence and presence of [Os(VIII)] catalyst in alkaline medium at a constant ionic strength of 0.10 mol dm−3 spectrophotometrically. The oxidation products were identified by spectral studies. The stiochiometry was same in both the cases, i.e., [GH]/[DPA] = 1:1. In both the catalyzed and uncatalyzed cases, the order of the reaction with respect to [DPA] was unity while the order with respect to [GH] was
