Abstract: Kinetics and mechanism of oxidation of formic and oxalic acids by benzyltriethylammonium chlorochromate (BTEACC) have been studied in dimethyl sulphoxide. The main product of oxidation is carbon dioxide. The reaction is first order with respect to BTEACC. The reaction is acid catalysed and the acid dependence has the form: kobs = a + b[H+]. The oxidation of α-deuterioformic acid exhibits a substantial primary kinetic isotope effect (kH/kD) =5.36 at 298 K). The reaction has been studied in nineteen different organic solvents and solvent effect analysed using Taft's and Swain's multiparametric equations. The temperature dependence of the kinetic isotope effect indicates the presence of a symmetrical cyclic transition state in the rate determining step.
