| Abstract: | The oxidation of glycollic, lactic, malic and a few substituted mandelic acids by quinolinium fluorochromate (QFC) in ethyl sulphoxide (DMSO) leads to the formation of corresponding oxoacids. The reaction is first order each in QFC and the roxy acids. The reaction is catalysed by the hydrogen ions. The hydrogen ion dependence has the form : kobs =a + b [H+]. dation of p-methylmandelic acid has been studied in 19 different organic solvents. The solvent effect has been analysed by g Kamlet's and Swain 's multiparametric equations. A mechanism involving a hydride ion transfer via a chromate ester is posed. |
