✦ Synopsis


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

The combination of P 4 S 10 , sulfur, and hexamethyldisiloxane converts 3-oxoesters to 3H-1,2-dithiole-3thiones in yields generally superior to those obtained with Lawesson's reagent and without the need for chromatography to remove large amounts of phosphorous-containing byproducts.
