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]

Structure

Thiete is a valence isomer of the compound thioacrolein (CH₂=CHCH=S) and undergoes ring opening to it at temperatures below 400 °C.^[5] Thiete has been shown to be planar, with a C-S-C angle of 76.8 degrees.^[6]

Derivatives

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.^[7]

Thiete 1,1-dioxides are sulfones, the parent being C₃H₄SO₂. They are more stable than the parent thietes.^[8] Substituted thiete-1,1-dioxides can also be prepared by [2+2] cycloaddition of sulfenes and ynamines.
