- A convenient one-pot method for the synthesis of symmetrical dialkyl trithiocarbonates using NH4OAc under mild neutral conditions
-
A facial, new, one-pot method for the preparation of symmetrical organic trithiocarbonates from various alkyl halides and carbon disulfide is described. This is a convenient, clean, and mild procedure, which involves the use of the neutral, nontoxic, commercially available, and inexpensive reagent NH4OAc in the preparation of the trithiocarbonate ion from carbon disulfide.

- 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.

- An efficient one-pot approach to the synthesis of symmetric trithiocarbonates from carbon disulfide and alkyl halides using imidazole
-
A novel method is reported for the synthesis of symmetric dialkyl 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.

- A novel one-step synthesis of symmetrical dialkyl trithiocarbonates in the presence of phase-transfer catalysis
-
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 CS2 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.

- Basic Al2O3 as an efficient heterogeneous reagent for the synthesis of symmerical dialkyl trithiocarbonates
-
This work deals with reaction of alkyl halides with carbon disulfide in the presence of basic alumina as heterogeneous and reusable reagent. It afforded symmetrical dialkyl trithiocarbonate in moderate to excellent isolated yields. Reaction of 1,2-dichloro ethane with carbon disulfide also proceeded in a similar manner to give a five-membered cyclic trithiocarbonate without formation of any polymeric by-product.

- Mild and efficient one-step synthesis of trithiocarbonates using minimum amount of CS2
-
Symmetrical dialkyl trithiocarbonates were obtained from various alkyl halides with an equivalent of carbon disulfide and cesium carbonate in polar aprotic solvents, although the conventional synthesis of trithiocarbonates had required large excess amount of carbon disulfide. This reaction proceeds under ambient conditions, for example, at room temperature under an aerial atmosphere, without strong base nor phase-transfer catalyst. Georg Thieme Verlag Stuttgart.
