Abstract
Pyridiniumbromochromate (PBC) in aqueous acetic acid oxidizes active methylene compounds to the corresponding triones. The -dc/dt is proportional to the concentrations of oxidant. Ther reaction is acid catalysed and the acid dependence has the form, kobs = a+b [H+]. The Michaelis-Menten type kinetics was discussed. The data can be correlated with mechanistic pathway involving the intermediate formation of chromite ester in pre-equilibrium in the transition state.
