Participants

Reaction Steps

A solution of 31.8 g. of 3-(2-methoxyethylthio)-1,2,4-triazole was dissolved in 300 ml. of acetic acid and heated to 80° C. To this solution was added by portions 67.2 ml. of 100 vol. hydrogen peroxide and the temperature was maintained at 80° C. for two hours with cooling as necessary in the early stages. A small amount of 10% palladium/charcoal catalyst was added to destroy excess hydrogen peroxide. After an hour the solution was filtered and sulphur dioxide passed through the mixture as a precaution in case peroxides had been formed. The solution was vacuum evaporated and crystals of the sulphonyl compound were removed. On the addition of further petroleum ether to the liquors, filtration and vacuum distillation, there was obtained an oily liquid, 3-(2-methoxyethylsulphinyl)-1,2,4-triazole. Elemental analysis satisfactory.
