A novel method is reported for the synthesis of symmetricdialkyl and cyclic (5, 6 and 7 member) trithiocarbonates from alkyl halides and carbon disulfide in the presence of imidazole and water in DMSO under mild reaction conditions. Imidazole is used as an inexpensive, non-toxic and readily available catalyst in this procedure. GRAPHICAL ABSTRACT

Symmetricaldialkyltrithiocarbonates were readily synthesized in excellent yields by one-step reaction of carbon disulfide and various alkyl halides under mild reaction conditions in the presence of cesium hydroxide as a super basic system. This method provides a synthesis of symmetricaldialkyltrithiocarbonates in short reaction times without the use of highly toxic starting materials. GRAPHICAL
