Article abstract of DOI:10.1016/S0040-4039(00)79295-1

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.
