Thiete is a heterocyclic compound containing an unsaturated four-membered ring with three carbon atoms and one sulfur atom.[1][2][3] It is more commonly encountered not on its own, but in anellated derivatives, several of which have been synthesized. Thietes are generally not very stable.[4]


Thiete is a valence isomer of the unknown compound thioacrolein (CH2=CHCH=S) Thiete has been shown to be planar, with a C-S-C angle of 76.8 degrees.[5]


Benzothietes are thietes annulated to benzo group. Such species are prepared by flash vacuum pyrolysis of 2-mercaptobenzyl alcohols. They are precursors to other S-heterocycles.[6]

Thiete 1,1-dioxides are sulfones, the parent being C3H4SO2. They are more stable than the parent thietes.[7] Substituted thiete-1,1-dioxides can also be prepared by [2+2] cycloaddition of sulfenes and ynamines.
