Dithietane


Dithietanes are saturated heterocyclic compounds that contain two divalent sulfur atoms and two sp-hybridized carbon centers. Two isomers are possible for this class of organosulfur compounds:
A stable 1,2-dithietane derivative is trans-3,4-diethyl-1,2-dithietane 1,1-dioxide, formed by the spontaneous dimerization of the lachrymatory agent syn-propanethial-S-oxide, found in onion.
