Dianions of 3-oxodithioic acids: Preparation and conversion to 3H-1,2-dithiole-3-thiones

Reaction of ketones with CS2 and 2 equivalents of KH in THF-N,N'-dimethylpropyleneurea solution produces the dianions of 3-oxodithioic acids. These dianions are converted in good yield to 3H-1,2-dithiole-3-thiones by the sequential action of hexamethyldisilathiane and an oxidizing agent such as hexachloroethane.

Reaction of 3-oxo dithioic acids with a combination of hexamethyldisilathiane and N-chlorosuccinimide in the presence of a catalytic amount of imidazole brings about oxidative ring closure to 3H-1,2-dithiole-3-thiones. Yields vary from poor to good.
