Symmetrical trithiocarbonates 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 CS 2 under phase‐transfer catalysis. In this manner, cyclic trithiocarbonates such as 1,3‐dithiolane‐2‐thione can also be prepared without formation of any polymeric by‐products.
