Reaction between Epoxides and Carbon Disulfide under Hydrotalcite Catalysis: Eco Compatible Synthesis of Cyclic Dithiocarbonates

Cyclic dithiocarbonates were prepared in good yield and excellent selectivity through an environmental acceptable methodology involving the reaction of substituted epoxides with carbon disulfide under hydrotalcite catalysis. The catalyst can be recovered by filtration and reused several times.
