A Mechanistic and Correlative Study on Sulfide Oxidation by Diethylammonium Chlorochromate

Abstract

The process of turning organic sulfides into their sulfoxides using diethylammonium chlorochromate (DEACC) occurred at first order concerning DEACC.  On the other hand, the reaction shows Michaelis–Menten-type kinetics when it comes to the sulfide substrate.  We used both single-parameter and multi-parameter correlation equations to conduct a kinetic study of thirty-four distinct sulfides.  Charton's LDR and LDRS equations gave the most accurate correlations for aryl methyl sulphides. The polar regression coefficients were negative in these cases.  The rate data for alkyl phenyl sulfides matched up quite well with the Pavelich–Taft equation.  Also, the oxidation of methyl phenyl sulfide was studied in nineteen distinct organic solvents.  Kamlet–Taft and Swain's multiparametric models were used to look at how the polarity and other properties of the solvent affected the reaction.  Based on the kinetic measurements, it has been suggested that a reaction mechanism includes the creation of a sulfurane intermediate during the phase that controls the rate.
