Symmetricaltrithiocarbonates were directly obtained, in moderate to excellent isolated yields, by the reaction of various primary, secondary, allylic and benzylic halides or alkyl tosylates with a suspension of granulated KOH and alumina in CS2 under phase-transfercatalysis. In this manner, cyclic trithiocarbonates such as 1,3-dithiolane-2-thione can also be prepared without formation of any polymeric
