Dithietanes are saturated heterocyclic compounds that contain two sulfur atoms and two sp3-hybridized carbon centers. Two isomers are possible for this class of organosulfur compounds, 1,2-dithietanes, where the sulfur atoms are adjacent, and 1,3-dithietanes, where the sulfur atoms are not adjacent. Organosulfur compounds are Organic compounds that contain Sulfur (sulphur Sulfur or sulphur (ˈsʌlfɚ see spelling below) is the Chemical element that has the Atomic number 16 An example of a 1,3-dithietane is [(CF3)2CS]2.
