Ethylene episulfoxide is the organosulfur compound with the formula C2H4SO. A colorless liquid, it is one of the simplest sulfoxides. Because it is a strained ring, ethylene sulfoxide is a highly reactive molecule, decomposing thermally to sulfur monoxide and ethylene. It is prepared by oxidation of ethylene sulfide with periodate.[1]
