Investigation of the oxidation reaction of various dithiocarbamates demonstrated that the corresponding sulfines (S-oxides) are formed. Though their stabilities are very moderate, a number of sulfines could be isolated and characterised. When left at ambient temperature they decomposed to thiolocarbamates and dithiocarbamates. The sulfines from secondary dithiocarbamates led to disulfides which formation was explained. With a sterically hindered aryl group present on the sulfur atom, a stable sulfine was prepared and its crystal structure was analysed.
