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 [Au III ] as well as [GA]. Both H + and Cl − ions retard the rate of reaction. AuCl 4 − , AuCl 3 (OH 2 ), and AuCl 3 (OH) − are the reactive species of gold(III) with gradually increasing reactivity. A reaction mechanism involving two‐electron transfer rate determining steps has been proposed. © 1998 John Wiley & Sons, Inc. Int J Chem Kinet: 30: 613–619, 1998
