It has been found that the reaction of the 1,2-ethanediylbis(trithiocarbonic acid) dianion with haloacetic esters, chloromethyl ethers, and chloromethyl sulfides in tetrahydrofuran proceeds smoothly to afford 1,2-ethanediylbis(alkoxycarbonylmethyl trithiocarbonates), 1,2-ethanediylbis(alkoxymethyl trithiocarbonates) and bis(alkylthiomethyl) trithiocarbonates plus ethylene trithiocarbonate respectively.

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.

Alkali metal alkoxides were studied as catalysts for the addition of CS2 to epoxides. A screening of several commercially available alkoxides revealed lithium tert-butoxide as an active and selective catalyst for this reaction. The influence of different reaction parameters as well as the substrate scope under optimized reaction conditions has been studied. Terminal and highly substituted epoxides as well as thiiranes were converted. In total 28 products were prepared and isolated in yields up to 95%. Notably, the reactions were performed under mild conditions without additional solvents. The regio- and stereoselectivity of the reaction has been studied e.g. by converting (R)-styrene and (R)-propylene oxide. Moreover, the test reaction was monitored by 13C NMR and a plausible mechanism for the conversion of terminal and internal epoxides is given. This proposal is in agreement with the observed regio- and stereoselectivity of the reaction.

We report an efficient one-pot route for the synthesis of symmetrical dialkyl trithiocarbonates from alkyl halides using carbon disulfide and a basic ionic liquid 1,1′-bis-methyl-3, 3-methylene-bisimidazolium dihydroxide as a reagent and phase-transfer catalyst.
