| has gloss | eng: Dithietes are unsaturated heterocyclic compounds that contain two sulfur atoms and two sp2-hybridized carbon centers. Having 6 π electrons, dithietes are aromatic. Two isomers are possible for this small class of organosulfur compounds, 1,2-dithietes, where the sulfur atoms are adjacent, and 1,3-dithietes, where the sulfur atoms are not adjacent. 1,3-Dithietes have not been isolated but a few 1,2-dithietes are known. Unsubstituted 1,2-Dithiete has been generated in thermolytic reactions and was characterized by microwave spectroscopy, UV-photoelectron spectroscopy and IR spectroscopy in low temperature matrix. The open ring structure, dithioglyoxal is less stable than 1,2-dithiete. |
