Abstract
The kinetics of oxidation of ethyl acetoacetate by þyridiniumbromochromate (PBC) in aqueous acetic acid medium yields α,-β-diketo acid as the main product. The stoichiometry corresponds to the reaction of two moles of PBC for 3 moles of substrate. The rate of reaction varies as a first power of concentration of oxidant. The reaction is being nearly first-order in acidity. The reaction does not induce polymerisation of acrylonitrile. The suggested rate law corresponds to the plausible reaction mechanism are discussed.
