Abstract

In acidic aqueous media the complex [AgIIILL−)3+[L = ethylenebis (bi-guanide)] reacts quantitatively with oxalic acid and bioxalate ion to produce CO2, Ag+ and L. Kinetic evidence indicates preequilibrium adduct formation, but the reactions appear to be outer-sphere with these adducts (I1 and I2) acting as kinetic dead ends.No Ag+ catalysis could be detected.
