WebUrea-hydrogen peroxide (UHP) was used in the presence of maleic anhydride as mediator in a simple and convenient method for the oxidation in high yield of some thiols to the corresponding disulfides. Peroxymaleic acid formed in situ from the reaction of UHP with maleic anhydride has a key role in this oxidation. Performance of the reaction in various … WebReactions of thiols with halogen derivatives in alcoholic medium in the presence of metal alkoxides may be regarded as a modification of the third procedure. Taber and Meagley [40] described the synthesis of 2-chloroethyl [13C]-methyl sulfide in which one step was the reaction of [13C]-methyl iodide with 2-sulfanylethanol in ethanol in the ...
