Abstract
A novel practical preparation method for methyl methanethiosulfonate (MMTS) has been developed. Dimethyl sulfoxide was converted to MMTS in the presence of a catalytic amount of oxalyl chloride or anhydrous HCl in acetonitrile under reflux in an ideal yield. Methanesulfenic acid was proposed to be the key intermediate for the formation of MMTS.
