Conditions

Temperature
100 °C

Procedure

A 50 g amount of dimethylsulfoxide and 10 g of methyl methanesulfonate were heated and stirred under reflux conditions at 100°C for 20 hours. The mixture was allowed to stand at room temperature and crystals of a product were collected by filtration. The crystals were then washed with acetone yielding 5.97 g of a white, crystalline product. When this product was recrystallized from alcohol, S,S,S-trimethylsulfoxonium methanesulfonate having a melting point of 222.0° to 222.5°C. (decomposition) was obtained.
