Thiete is a heterocyclic compound containing an unsaturated four-membered ring with three carbon atoms and one sulfur atom.{{cite journal |last= Leśniak |first=S |author2=Lewkowski, J |author3=Kudelska, W |author4= Zając, A | title =Thietanes and Thietes: Monocyclic |journal =Comprehensive Heterocyclic Chemistry III |year=2008 |volume=2 |issue=7 |pages=389–428 |doi=10.1016/B978-008044992-0.00207-8}}{{cite journal |last=Block |first=E |title=Thietes and Derivatives |journal =Sci.

Thietes are generally not very stable.{{cite journal |last=Dittmer|first=DC|author2=Davis, FA| title=Evidence for a Thiete (Thiacyclobutene) |journal =J. Am. Chem.
