✦ Synopsis

The kinetics of the reaction between glycolaldehyde (GA) and tetrachloroaurate(III) in acetic acid-sodium acetate buffer has been studied. The reaction is first-order with respect to as well as [GA]. Both and ions retard the rate of reaction. III ϩ Ϫ Ϫ [Au ] H Cl AuCl , 4 and are the reactive species of gold(III) with gradually increasing Ϫ AuCl (OH ), AuCl (OH) 3 2 3 reactivity. A reaction mechanism involving two-electron transfer rate determining steps has been proposed.

Diperiodatoargentate(III) oxidizes nitrilotriacetic acid in a mildly basic medium to produce formaldehyde and ammonia. This reaction follows a complex kinetic behaviour. The axial binding of NTA to silver(III) complex takes place on the millisecond time-scale with a second-order rate constant of (4.

The oxidation of ethylenediamine by diperiodatoargentate (III) ion has been studied by stopped-flow spectrophotometry. Kinetics of this reaction involves two steps. The first step is the complexation of silver (III) with the substrate and is over in about 10 ms. This is followed by a redox reaction
