Abstract
This chapter is an update to the earlier Science of Synthesis contribution describing methods of synthesis and new applications for thiocarbonyl S-oxides (sulfines) and thiocarbonyl S-imides. In general, thiocarbonyl S-oxides are more stable and in many instances can be isolated. The in situ generated thiocarbonyl S-imides are efficient “sulfur-transfer agents” via the isomeric thiaziridines, formed as products of electrocyclic ring closure. Stable thiocarbonyl S-imides, derived from hexafluorothioacetone, are useful 1,3-dipoles and are applied in the preparation of fluorinated five-membered heterocycles.
