Oxidation of thirty six mo nosubsti tuted benzaldehydes by quinolinium chlorochromate (QCC) in dimethylsulfoxide (DMSO), leads to the formation of corresponding benzoic acids. The reaction is of first order with respect to QCC. A Michaelis-Menten type kinetics was observed with respect to the reactants. The reaction is promoted by hydrogen ions; the hydrogen ion dependence has the form kobs = a + b[H+]. The oxidation of benzaldehyde (PhCDO) exhibited a substantial primary kinetic isotope effect. The reaction was studied in nineteen different organic solvents and the efiect of solvent was analyzed using Taft’s and Swain’s main-parametric equations. The rates of the oxidation of para and meta substituted benzaldehydes showed excellent correlation in terms of Charton’s triparametric LDR equation, whereas the oxidation of ortho-substi tu ted benzaldehydes were correlated well with tetraperametric LDRS equation. The oxidation of para-substituted benzaldehydes is more susceptible to the delocalized effect than the oxidation of ortho- and meta-substituted compounds, which display a greater dependence on the field effect. The pos. value of h suggests the presence of an electron-deficient reaction center in the rate-determining step. The reaction is subjected to steric acceleration by the ortho-substituents. A suitable mechanism has been proposed.
