Acid-Catalyzed Hydrolysis of 1,1-Bis(methylthio)ethene. Buffer- and Thiol-Dependent Changes in the Rate-Determining Step

Acid-catalyzed hydrolysis of 1,1-bis(methylthio)ethene has been studied kinetically in 10percent aqueous acetonitrile at 30 deg C.The rate increased with buffer concentration, showing saturation at higher concentrations.Addition of 2-mercaptoethanol had little influence on the rate at the limiting zero buffer concentration, but it greatly accelerated the reaction in buffer solutions and followed a saturation curve.It was concluded that the rate-determining step is largely the protonation of the double bond at zero buffer concentration (k2/k-1 = 3.13) but it changes to the attack of water on the intermediate carbenium ion as the buffer concentration increases.The 1H NMR spectral analysis of the reaction products in 80percent CH3CN-D2O showed that the H-D isotope exchange at the 2-position of the substrate occurred extensively in a formate buffer but only moderatly in a DCl solution during the hydrolysis.

Convenient synthesis of alkyl thioacetate from alkyl halide using a polymer-supported sodium thioacetate

Alkyl halides are efficiently converted to their corresponding S-alkyl thioacetates under mild and nonaqueous conditions, using polymer-supported sodium thioacetate as a new polymeric reagent at room temperature in high yields and purity. The spent polymeric reagent can be removed quantitatively by filtration and pure products can be obtained by evaporation of the solvent. The spent polymeric reagent can be regenerated and reused several times without its activity changing appreciably. Iranian Chemical Society 2012.
