Basic Al₂O₃ as an Efficient Heterogeneous Reagent for the Synthesis of Symmerical Dialkyl Trithiocarbonates

Abstract

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.

Keywords:

• Basic alumina
• cyclic trithiocarbonate
• symmetrical dialkyl trithiocarbonate
