Symmetrical dialkyl trithiocarbonates were readily snythesized in excellent yields from alkyl halides and carbon disulfide under mild reaction condition in the presence of a regenerable hydroxide form of an anion exchange resin.

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.
