✦ Synopsis

The reaction between tetrachloroaurate(III) and malonic acidfmalonate ion was studied kinetically over a wide range of temperatures, malonate, hydrogen and chloride ion concentrations at ionic strength 1.0 M. The suggested reaction mechanism consists of a series of substitution reactions during which Au(III) malonato chloride species are produced. These species undergo a redox reaction for which the rate constant was determined radiochemically as 1.1 X 10m5 set-' at 40 "C. Kinetic evidence for some form of catalytic action by chloride ion is reported, and the results are discussed with reference to literature data.
