Abstract
KINETIC studies of the decarboxylation of phenylmalonic acid in aqueous solution in the presence of high concentrations of rare-earth ions show that diamagnetic ions have little effect on the rate of reaction, while the paramagnetic dysprosium ion leads to an acceleration in rate of the order of 10 per cent1,2. Rare-earth ions do not appear to become co-ordinated appreciably with phenylmalonic acid. Since any magnetic effect must be a very sensitive function of the distance between catalyst and substrate, a study is now being made of the kinetics of decarboxylation of an acid, the anions of which are known to become co-ordinated more strongly with metal ions.
