Superbasic system CsOH/DMSO as a reagent for a fast one-step synthesis of symmetrical dialkyl trithiocarbonates

Symmetrical dialkyl trithiocarbonates 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 symmetrical dialkyl trithiocarbonates in short reaction times without the use of highly toxic starting materials.
